TRAC10248 PH LORAWAN SENSOR is a wireless communication device for pH value of acid, alkali, and salt solution. TRAC10248 PH LORAWAN SENSOR can detect the pH value and temperature of the solution. The body and the pH sensor are connected through the RS485 interface, and the detected data is transmitted to other devices through the wireless network for display. It adopts the wireless communication method that conforms to the LoRaTM protocol standard.
