WisNode Sense Home

Product Description

The WIsNode Sense Home (RAK7204) is an LPWAN node that serves as an environmental monitoring station. The high-precision sensors, can measure changes in temperature, humidity, gas pressure, and provide an indoor air quality index.
All the accumulated data can be sent to a LoRaWAN® gateway in order for it to be forwarded to the Cloud.
Because of its design, WisNode Sense Home can achieve a very low power consumption rate, which with the included non-rechargeable battery allows for 2+ years of operation.
The firmware has built-in functionality that allows the user to adjust the sampling interval of the sensors and the transmission cycle.
Last but not least, WisNode Sense Home adopts a highly integrated design, fitting the electronics and battery within 90mm x 85mm x 34mm casing.
