Remotely collect water pH levels with Netvox‘s RA0708 LoRaWAN® pH measurement sensor. Ideal for areas where water quality is of utmost importance, the Netvox RA0708 is ideal for:

  • Monitoring the effects of pollution in water sources
  • Maintaining regular records in public areas
  • Assessing suitability for aquatic life and/or for Livestock to drink from

The pH measurement sensor uses LoRaWAN® technology and the SX1276 wireless communication module to record and transmit data over a range of up to 10km. Recorded data is transmitted by a LoRaWAN® gateway and network server to your chosen platform. Users can then view and interpret the recorded information via the dashboard.

Users can also configure this sensor to raise SMS or email alerts to notify them of data recorded outside of their set parameters.
