In modern storage facilities, controlling temperature and humidity together is a prerequisite for maintaining product quality. A dedicated cold storage temperature sensor not only measures deep sub-zero temperatures accurately down to -50°C but also monitors humidity (0-100% RH), making it a perfect fit for specialised environments such as fruit storage rooms, mushroom houses and livestock farms.
At Tân Long, with hands-on experience in cold storage design and installation, we recommend sensors rated IP54 or better for durability in damp conditions while keeping costs sensible for the owner. Connected to a PLC control cabinetsystem, the sensor becomes the watchful eye that lets a business monitor conditions and receive fault alerts 24/7, fully protecting the value of its produce and food products.

What is a cold storage temperature sensor? Construction and its key role
Cold storage temperature sensor is a dedicated instrument that measures, monitors and continuously reports temperature variation inside a storage environment. When temperature or humidity changes, the device sends an electrical signal back to a readout unit or a PLC control panel. There the electronic signals are processed and converted into a clear temperature reading, so technicians can keep operations under control.
Unlike ordinary thermometers or thermocouples, a cold storage temperature sensor is designed for very high accuracy and for deep sub-zero service. On standard cold storage design projects, Tân Long favours sensors with a wide measuring range (-50°C to +50°C) rated at least IP54 for water ingress. Their durability in damp conditions makes them the first choice for industries with demanding storage requirements: food, pharmaceuticals, chemicals and electronic component manufacturing.
In industrial practice, a cold storage temperature sensor also goes by several other names — thermocouple, resistance thermometer, or temperature sensor. Depending on the specific requirements of each cold storage installationsystem, you can choose the appropriate probe type:
- PT100 probe: The most widely used sensor in cold storage, thanks to its stability and near-absolute accuracy across the sub-zero range.
- Type J, K, T and E thermocouples: Typically used for general-purpose temperature measurement.
- Type B, R and S thermocouples: Designed for extremely high temperatures, and rarely seen in industrial refrigeration applications.
For specialised facilities such as fruit storage rooms or mushroom houses in particular, a cold storage temperature sensor with integrated humidity measurement (0-100% RH) is the best way to keep produce fresh for longer.

Standard technical specifications for cold storage temperature and humidity sensors
In the systems industrial cold storage a modern facility needs measuring instruments that are durable in harsh conditions. A cold storage temperature sensor with integrated humidity monitoring is usually designed with a wide measuring range — typically -50°C to +50°C for temperature and 0-100% RH for humidity — together with a water and dust ingress rating of at least IP54, so the device runs reliably and is not damaged by condensation.
Based on Tân Long's practical cold storage design experience, this specification comfortably covers the needs of food, pharmaceutical and agricultural storage. An owner can of course choose sensors with a higher IP rating or a wider range, but that generally raises capital cost considerably without delivering a clear advantage. Prioritising high-sensitivity devices that integrate cleanly with the PLC control panel is the better answer.
Versatile applications of cold storage temperature sensors in agriculture and livestock farming
In modern livestock farming, controlling the micro-climate inside the shed is critical to animal health and productivity. Using a cold storage temperature sensor with integrated humidity measurement lets the farm owner track environmental conditions closely. It keeps the animals comfortable and minimises disease arising from sudden swings in temperature and humidity.
The cold storage temperature sensor designed for farm use is built to withstand the specific conditions found in pig, chicken, duck and cattle sheds — heavy dust, moisture and ammonia. Monitoring and adjusting the animals' living conditions therefore becomes more accurate and effective than ever.

Smart monitoring solutions with temperature and humidity sensors
Combining temperature and humidity measurement in one device makes for a far better automatic monitoring system. Today's cold storage temperature sensor are typically highly accurate, support remote data transmission and integrate easily into a PLC control panel.
With a wide measuring range of -50°C to +50°C, the device is not just for livestock sheds — it is also the first choice for food cold storage and produce warehouses, keeping measurement error to a minimum.
Humidity and temperature sensors for mushroom growers
In a mushroom house, humidity is held very high, so the measuring device must have excellent water resistance. Cold storage temperature sensor with a deep sub-zero range and industrial-grade durability is the best way to monitor environmental conditions, creating ideal conditions for mushrooms to grow evenly and yield well.
Monitoring temperature and humidity in fruit storage rooms
Maintaining stable air quality in cold storage design for fruit is extremely important. Using an IP54-rated instrument keeps the sensor working reliably where condensation is heavy. The water-resistant design of the cold storage temperature sensor also allows flexible use outdoors, in greenhouses and in factories with harsh conditions.

Optimising cost with temperature sensors for farms
In Tan Long, we offer the following lines cold storage temperature sensor and humidity, measuring accurately both indoors and outdoors. The device includes intelligent alarm functions, letting managers stay on top of conditions from the office or the plant floor. Compared with ordinary measuring instruments, Tân Long's solution delivers far better value thanks to its durability, breadth of features and the most competitive price on the market.
Usage temperature and humidity sensor in various fields has proven to be highly effective in monitoring and maintaining ideal environments. From cold storageFrom livestock farms to greenhouses to farms, these sensors not only help protect products but also enhance performance and reduce risks.
Frequently asked questions about cold storage temperature sensors
What is a cold storage temperature sensor?
It is a device that measures the temperature inside a cold room and sends the signal to a controller or monitoring system, providing the basis on which the refrigeration system switches and temperature data is logged.
Where should the sensor be positioned in a cold store?
At a position representative of the temperature of the stored goods. Avoid placing it close to the evaporator, near the door, or in a direct airflow — those locations give readings that differ from the product's actual temperature.
Why should a cold store have more than one sensor?
Because temperature in a store is not uniform everywhere. Several sensors placed at the warm and cold spots reveal dead zones and demonstrate that the whole store meets requirements, not just one point.
Do temperature sensors need calibration?
Yes. In stores serving food and pharmaceuticals, sensors must be calibrated on a regular schedule with the records retained, because that data is the evidence that goods were held under the correct conditions.
What are the signs of a faulty temperature sensor?
The displayed value differs markedly from a reference thermometer, the reading jumps erratically or stays frozen, the controller reports a sensor fault code, and the system switches outside its normal logic.
What are the benefits of remote temperature monitoring?
It lets you receive an alert the moment temperature exceeds the threshold, even outside working hours, keeps data for traceability and quality records, and helps you spot abnormal trends before they become faults.
