Product description: Wireless barometer SenseCAP - LoRaWAN 868 MHz - Seeedstudio 114991729
Wireless sensor of atmospheric pressure SenseCAP, allowing measurements at the range from 300 hPa to 1100 hPa. The Seedstudio's product provides accurate measurement and stable performance so that the barometer is perfect both in industrial and in home gardens. For power supply, device uses a battery with a voltage of 3.6 V. The manufacturer claims that the lifespan of the internal battery is about3 years.
Method of installation and mounting of the barometer SenseCAP.
Communication interface LoRaWAN
For wireless communication, sensor uses the LoRaWAN protocol. This type of communication has a similar working principle to GSM network known to everyone, end devices transmit data to the base station which transmits data to the server from which we can view and analyze the data. There is also the possibility of creating your own network by purchasing the LoRaWANgate. The great advantage of this technology is the distance at which data can be transmitted, even up to tens of kilometers.
Scheme of communication in LoRaWAN technology.
Work of Seeedstudio SenseCAP barometer
Wireless barometer is widely used in projects related to intelligent agriculture or in projects collecting and analyzing the data on the prevailing environmental conditions. The manufacturer also described the cases of using this barometer and the other sensors of this series in user projects:
- The cultivation of triticalein the open farm of a precise agriculture
- The cultivation of melonsin a demonstration park of intelligent agriculture
- Tropical fruit cultivationin smart greenhouses
- Intelligent tea plantation
- Projects monitoring environmental conditions inStockholm and inHeyuan
Thanks to using the LoRaWAN technology, sensor can transmit data at very long distances.
The design of the SenseCAP sensor
SenseCAPare the two-part modular sensors.One is a moduleof the sensor together with the probe and the second is the module that containsthe restof the systems which are responsible for power and data transmission. The sensor module may be alternately used with the main modules of other SenseCAP sensors.
