Seeed Studio MODBUS-RTU RS485 & 0-2V Analog Voltage

It measures Conductivity, Salinity, TDS with temperature compensation, making it widely applicable in industrial environmental sensing scenarios. We have two versions Industrial EC & TDS Sensor. The main difference is the cable connector. Please choose the version that best suits your needs （1）This one is with a waterproof aviation connector. It is compatible with SenseCAP Sensor Hub 4G Data Logger, which can collect various sensor data simultaneously and send them via 3G/4G LTE. （2） Another version is with hook-up wires. It is compatible with SenseCAP LoRaWAN® Data Logger to connect with the LoRaWAN® network, enjoying the benefits of low-power and long-range communication. Applications : Agriculture, Hydroponics, Aquaponics, Sewage treatment, Research, Environmental monitoring and Other environmental monitoring scenarios. This EC & TDS Sensor with a waterproof aviation connector measures the conductivity, salinity, and total dissolved solids (TDS) in a liquid and is widely used in monitoring water quality. The EC & TDS Sensor is designed with industry standards. It is designed with ATC (automatic temperature compensation), which ensures the data is accurate regardless of the temperature changes. Its electrode is IP68, the transmitter is IP65 rated, waterproof in a tight seal, and capable of withstanding long-term constant use in professional scenarios. This EC & TDS Sensor comes with a MODBUS-RTU RS485 serial communications protocol and 0~2V Analog Voltage output. It can be easily connected and integrated with other devices such as data loggers, Converter, and displays. This cost-effective EC & TDS Sensor features low-power consumption, compact size, portability, and high integration. Seeed also provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.
