Misol WH52 soil sensor 433Mhz, soil moisture, soil temperature, soil EC, Soil Electrical Conductivity sensor

Features: * IP66 Waterproof: Built to IP66 standards to withstand harsh outdoor environments. Includes silicone protective caps for enhanced water resistance in extreme conditions. * Wireless Transmission & Simple LED Indication: The probe body has no screen; it transmits data via RF signal to a compatible gateway or console for analysis. A simple red LED on the body clearly indicates data transmission status and operational faults. * Long Range Wireless Range: Capable of strong wireless transmission up to 100 meters under standard conditions (in the open field, no obstacle, no signal interference). *Safe Sensor Installation: To ensure accurate readings and prevent damage, the sensor must be placed in a pre-dug hole; avoid forcing it into hard, compacted soil. For standard use, the probe should be buried up to the depth marker on the body.
