Neuron Temperature IP21

The Neuron Temperature IP21 is a small wireless sensor with long battery life that measures ambient air temperature every three seconds. It transmits measurements wirelessly through a Neuron gateway to the Neuron app. Typical applications are monitoring of temperature in all types of rooms and buildings, refrigerators, freezers and fuse boxes. The sensor is attached with double-sided tape or cable tie.

General Description

Temperature is a crucial parameter in many different applications, from HVAC systems and industrial process maintenance to freezers. Accurate measurement of ambient temperature is therefore essential for maintaining optimal conditions and ensuring proper functioning of these systems.

The Neuron Temperature IP21 sensor is a high- precision device designed specifically for measuring the temperature of air. With a wide temperature range of -40°C to 85°C and an accuracy of ±0.5°C, this sensor is ideal for a variety of applications where temperature needs to be monitored and controlled with a high degree of accuracy.

Compact in size at just 37mm x 25mm x 14mm, the sensor is easy to integrate into any system. It operates on a non-replaceable integrated battery allowing it to operate up to 10 years.

Whether you need to monitor the temperature in a warehouse, control the temperature in a refrigerator, or monitor HVAC-systems, the Neuron Temperature IP21 sensor is the perfect choice for reliable and accurate temperature measurement.

 

Principle of Operation

In the Neuron Temperature IP21 sensor, an NTC thermistor is used as the sensing element. The thermistor is placed in direct contact with the air, allowing it to accurately measure the ambient temperature.

The thermistor’s resistance is measured by passing a small current through it and measuring the voltage across it. This voltage is then used to calculate the thermistor’s resistance, and from that the ambient temperature can be inferred.

The Temperature IP21 sensor has high accuracy, wide temperature range, robust IP21 enclosure, and fast response time.

Every three second the sensor measures the ambient temperature and if the temperature has changed more than 2 degrees since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.

Installation

Neuron sensors are ready for use out of the box and will start logging data after registering the sensor in the app. Even though Neuron sensors deliver great range and long battery life, following some simple guidelines for mounting of the sensor and gateway can greatly improve signal coverage and lifetime of the sensor.

To ensure optimal antenna performance and signal strength, the sensor should be placed elevated with some distance to fixed objects. Keep in mind that RF-signals are greatly affected by close metallic surfaces.

For sensors with an external antenna, the antenna should be clear off the metallic surface.

For sensors operating in environments with greatly varying temperatures, care should be taken to avoid putting the sensor in unnecessary stress. Very high or low temperatures will affect the battery life and the signal strength of the sensor. While some sensors must be close to the source of heat or cold, other sensors have external probes which allow the sensor to be placed at a distance.

Fastening
The small, compact blue Neuron sensors are fitted with fastening holes for use with cable ties. The sensors are also delivered with double-sided tape that may be used for fastening of the sensors.

All the black Neuron sensors, like the Neuron IR380 and Neuron Vibration, are fitted with a strong magnet at the back for easy fastening. If there is no magnetic surface, then double-sided tape is a good solution.
