RS485 Soil Moisture, Temperature, and EC Sensor IP68 5-30V

The RS485 Soil Moisture, Temperature, and EC sensor offers you precise monitoring of soil conditions right on your field. Equipped with the latest technology, this sensor not only measures humidity and temperature, but also the electrical conductivity (EC), which is crucial for assessing the soil salinity. The robust construction with an IP68 protection class and a probe made of 316 stainless steel makes the sensor water, corrosion and salt resistant. The reliable RS485 interface guarantees secure data transmission using the MODBUS-RTU protocol. This sensor is particularly suitable for applications in agriculture, greenhouse operations and scientific experiments where precise data is required. The easy installation and long service life reduce maintenance effort and ensure continuous performance.

Recommended accessories:

• RS485 Shield for Arduino UNO
• Industrial USB to RS232/485 Converter FT232RNL
• SenseCAP S2100 LoRaWAN Data Logger

Features:

• Measures soil moisture, temperature and electrical conductivity.
• High measurement accuracy due to automatic temperature compensation of the EC measurement.
• Resistant to water, corrosion and salt due to 316 stainless steel probe.
• Data transfer via RS485 interface and MODBUS-RTU protocol.
• IP68 protection class for use under extreme conditions.

Application examples:

• Monitoring soil conditions in agricultural operations to optimize irrigation.
• Use in greenhouses to control the microclimate and promote plant growth.
• Scientific studies to analyze the influence of soil conditions on plant growth.
• Long-term monitoring in ecological restoration projects.
• Precise soil tests in landscaping and in the cultivation of rare plant species.
