The 4-20 mA Sensor Board allows the user to interface the Waspmote ecosystem with 4-20 mA systems. Waspmote allows to perform two main applications:
1º- Add wireless connectivity to 4-20 mA devices
Waspmote can be configured to read the information coming from 4-20 mA sensors and send it wirelessly using any of the wireless modules available in the platform to a base station or to another node connected to another bus. The available wireless technologies are: 802.15.4, ZigBee, DigiMesh, 868 MHz, 900 MHz, LoRa, WiFi, GPRS, GPRS+GPS, 3G, 4G, Sigfox, LoRaWAN, Bluetooth Pro, Bluetooth Low Energy and RFID/NFC.
2º- Connect to the Cloud 4-20 mA devices
Waspmote can be configured to read the information coming from the 4-20 mA sensors and send it wirelessly directly to the Cloud using WiFi, GPRS, GPRS+GPS, 3G and 4G radio interfaces.
