This product is a leaf temperature and humidity transmitter that uses RS485 (Modbus RTU) interface. Its humidity sensor is based on the principle of dielectric constant measurement, designed to mimic the geometric shape of real leaves, and can sensitively detect small residual moisture on the leaf surface; The temperature sensor adopts high-precision thermistor for precise measurement across the entire range. Main technical parameters: temperature range -40~80 ℃, accuracy ± 0.5 ℃; Humidity range 0~100% RH, accuracy ± 3% RH (@ 25 ℃). The whole machine is encapsulated with epoxy resin, with a protection level of IP67, wide voltage power supply DC 4.5-30V, low power consumption, and customizable wire length. Suitable for continuous monitoring of plant leaf or object surface humidity in scenarios such as greenhouses, laboratories, livestock farms, and artificial climate chambers.

The ZONEWU RS485 integrated three-in-one soil sensor (temperature, humidity, EC) combines soil moisture, temperature, and electrical conductivity detection in a single streamlined device. It offers practical advantages like easy portability for flexible deployment, reliable sealing to resist moisture, dust, and corrosion, and high measurement accuracy for consistent, trustworthy data. Ideal for professionals needing comprehensive soil parameter monitoring, it suits agriculture (optimizing irrigation/fertilization), horticulture, environmental monitoring, and scientific research. Eliminating the need for separate sensors, it simplifies installation and operation while providing a holistic view of soil conditions to support informed decision-making.

ZONEWU RS485 Soil Temperature and Humidity Sensor integrates soil moisture and soil temperature sensors, and has the advantages of easy portability, sealing, and high accuracy. It is an ideal choice for measuring soil moisture and soil temperature.
