ZTS-3000-TR-SD-N01 Soil Sensor

Depending on the specific configuration of the ZTS-3000 series, this model typically monitors:

• Soil Moisture: Measures volumetric water content from 0–100%.
• Soil Temperature: Usually tracks a range from -30°C to +70°C (or up to +80°C).
• Electrical Conductivity (EC): Measures soil salinity, which is crucial for managing fertilizer levels.

Wiring Guide (Color Code)

The bundled cable usually follows a standard four-wire color scheme:

• Red: Power Supply (VCC, 5–24V DC)
• Black: Power Ground (GND)
• Yellow: RS485-A
• White: RS485-B

Usage Tips

• Installation: Insert the steel needles vertically into the soil. Ensure they do not hit stones or hard objects, as this can bend the needles or cause inaccurate readings.
• Communication: Because it uses RS485/Modbus, you will need an RS485-to-USB adapter to read data on a computer, or an RS485-to-TTL module if you are connecting it to a microcontroller like an Arduino or ESP32.
• Maintenance: Avoid leaving the sensor powered on for long periods in open air; it is designed to be energized while inserted into a medium (soil or water).
