Feature: 1. Simulation of the structure design of the leaf surface, so that the sensor can truly reflect the process of moisture loss. 2. Applicable to a variety of tests, can detect fog, ice, dew and rainfall. 3. High precision, high accuracy, quick response, good interchangeability and reliable performance. 4. Monitor leaf temperature and humidity. Can monitor the leaves of trace moisture or ice crystal residue, early warning plant diseases and insect pests. 5. Low power consumption for long-term monitoring. The leaf imitation design can simulate the real leaf surface environment with stable performance and high sensitivity. 6. IP65 high protection level, waterproof seal can be directly applied to foliar fertilization, spraying irrigation occasions, can be used outdoors. 7. Lightweight, easy to install. It can be hung from a greenhouse or mounted on the mast of a weather station. 8. Widely used in early warning of plant diseases and insect pests, field crops early warning, agrometeorology, intelligent agriculture, etc. Specification: Condition: 100% Brand New Item Type: Leaf Surface Temperature Humidity Sensor Material: ABS Color: As shown in the picture Size: Approx.170x80mm / 6.7x3.1in Weight: Approx.195g/6.9oz Power Supply: DC9-24v Communication Standard: RS485 Temperature Range: Leaf surface temperature: -20C~80°C Humidity Range: Leaf surface humidity: 0%~100% Temperature Resolution: 0.01°C Humidity Resolution: 0.1%RH Temperature Accuracy: ±1°C(@25°C) Humidity Accuracy: ±5%RH(@25°C) Operating Environment: 40°C~80°C Wiring Instructions: Brown: Power supply positive pole Black: Power supply negative pole Blue: 485-A Yellow: 485-B.
