Displaying data from RHF1S001 in node-red


rhf1s001The RisingHF’s Temperature and humidity LoRaWAN sensor node RHF1S001 is aimed at outdoor application with it’s IP64 protection level. And thanks to it’s high performance internal antenna and LoRa technology used, the sensor could operate in extremely hard environment or ultra-long range application. In addition to all above, the ultra-low sleep current help it to work in a long life, 5 years (uplink every 2 minutes) or even 10 (uplink every 5 minutes) years.

Here is sample code to displaying data to dashboard node-red, Raw data taken from MQTT convert to JSON Object.
