Seeed Technology 101990666 - Seeed Industrial RS485/Modbus bare wire pH IoT Sensor

Description

The Seeed studio industrial-grade IoT MODBUS-RTU RS485 pH meter/sensor features ATC, low-power-consumption and high integration. It can be widely used in monitoring pH levels in soil and water applications such as agriculture, gardening, horticulture, swimming pools, scientific experiments, and other environmental monitoring scenarios. Comes with bare wire connectors to add to any Modbus/RS485 IoT deployment.

This pH IoT sensor (S-pH-01A) is designed with industry standards. It adopts international advanced solid dielectric and large-area polytetrafluoroethylene liquid junction, which is not easy to block and convenient for maintenance. It's designed with ATC (automatic temperature compensation), making sure the data is accurate regardless of the temperature changes. This pH Sensor is IP65 rated, waterproof in a tight seal, capable of withstanding long-term constant use in professional application scenarios.
