Product description: SenseCAP wireless air humidity and temperature sensor - LoRaWAN 868MHz - Seeedstudio 114991726.
TheSenseCAP air humidity and temperaturesensor, equipped with a wireless communication module, enables measurement of ambient temperaturefrom -40°C to 85°C andhumidity from 0%to100% RH.The sensor ofSeeedstudiocompany is characterized by precise measurement and reliable operation, which makes the product suitable for both industrial and home projects. The device uses a3.6 Vbattery for power supply. The manufacturer declares the life of the built-in battery for about3 years.
Installation and assembly of the SenseCAP sensor.
LoRaWAN communication interface
The product communicates using theLoRaWANprotocol, which works in a way similar to the GSM network, the sensors send data to the base station, from where the data are sent to a server from which we can display and analyze data. The LoRaWAN interface also allows to create private networks. This type of technology is characterized by a longrange ofoperation, which makes it possible to connect to the sensors even several kilometres away.
Communication scheme using the LoRaWAN interface.
Operation of air humidity and temperature sensor
The sensor will be perfect for all projects related to Intelligent Agricultureand weather stations monitoringenvironmental conditions. The manufacturer has also described cases of using this and other sensors from this series in user projects:
- Triticale cultivationon an outdoor precision farm
- Growing melons ina demonstration park for intelligent agriculture
- Tropical fruit cultivation inintelligent greenhouses
- Intelligent tea plantation
- Environmental monitoring projects in StockholmandHeyuan
The sensor communicates with the LoRaWAN communication system.
SenseCAP sensor design
SenseCAPsensorsconsist of two modules, one of which is the sensor with the probe and the other is the main module containing the data storage system, communication module and battery.

Remote communication sensor designed for professional applications
The SenseCAP air temperature and humidity sensor from SeeedStudio, thanks to its IP66 rating, can operate on objects with adverse environmental conditions. What distinguishes SenseCAP from standard measurement sensors is its high measurement accuracy and wide range of wireless communication possibilities with measurement systems. Using the LoRaWAN communication protocol, we can remotely monitor the temperature and humidity measured by SenseCAP and save the measurement results to the data cloud through a dedicated application.
Temperature and humidity measurements in practice
Air temperature and humidity are parameters which in many cases seriously affect the correctness and quality of many different biological and technological processes. In the mining, metallurgical and chemical industries, excessive air humidity reduces the oxygen concentration in the air. Such a state negatively translates into full utilization of the calorific value of fossil fuels necessary to produce thermal energy used to heat water in power plants and combined heat and power plants. Maintaining an appropriate level of humidity is also a problem for plant crops. Plants require enough water in the soil to develop properly. Not enough water can cause rapid dying, while too much humidity promotes the development of mould spores, which are carcinogenic. The SenseCAP Wireless Temperature and Moisture Sensor allows real-time measurements and can work with automatically controlled irrigation and dehumidification devices.
