How to choose a temperature and humidity sensor?

The IoT temperature and humidity sensors are among the most commonly used IoT devices. These provide the actual temperature or/and humidity conditions within the air in indoor or outdoor environments.

If you are considering buying a temperature or humidity sensor or looking to upgrade, our guide for choosing the best one will help you understand the different types of devices and their latest features. Even if you already own one of these sensors, this guide can help you get to know more about it so you can maximize its functions. 

How do they work?

Temperature and humidity sensors work by monitoring changes that alter electrical currents or temperature in the air. A humidity sensor measures humidity by placing a thin strip of metal oxide between two electrodes. The metal oxide’s electrical capacity changes with the atmosphere’s relative humidity and the data get collected and sent.

You can currently find various types of temperature and humidity sensors on the market, the most common technologies being Thermocouples, RTDs, Thermistors, and IC Temperature Sensors.

If you are looking for an easy to deploy all-in-one device, Radio Bridge offers a sensor that uses airflow to measure temperature and humidity levels. If these rise above or fall below configurated thresholds, the device will send an alert to the wireless network. The device can be used to monitor room temperature and humidity levels, detect freezing temperatures to protect plumbing, detect heat failure in second homes or remote buildings or cooling system failures, for industrial temperature monitoring, or as a general temperature/humidity sensor.

Other companies, like Giga Concep, have created small and sleek sensors which can be easily disguised to monitor temperature and humidity in indoor areas, without making the room appear full of devices.

ATIM has created a digital temperature sensor in a plug-and-play format, for easy use. The solution allows to collection of information from a remote digital temperature probe, which comes included, over long distances, covering a range of up to 15 km. The data then gets uploaded to local wireless infrastructure or a cloud platform via an LPWAN network dedicated to IoT.

Lastly, if you are seeking high precision,  Lansitec offers an extremely accurate smart sensor that allows up to 5 years of operation, with an extended operating temperature for industrial use cases, which goes from -40°C to 85°C. the device is compatible with a large variety of use cases like weather stations, heating and drying measuring ventilation and air conditioning systems controlling smart agriculture, or smart building solutions.

Your IoT project will benefit from the most useful features

Most sensors use high-performing, power-efficient, and low-cost IoT multi-technology for LoRaWAN™, offering an advanced service quality and extended battery life.

Smart sensors offer:

  • Long battery lifetime is achieved by low peak current, which allows batteries to work at maximum capacity, offering continuous use of devices for months or years.
  • High sensitivity and accuracy. These sensors can embed multiple technologies to offer the highest precision.
  • Light and high resistance
