Feature:1. MONITOR ANYTIME: You can connect the transmitter to the environmental monitoring host or network concentrator, and you can view the data at any time through the mobile computer.2. ANTI INTERFERENCE: The transmitter has a built in waterproof temperature and humidity collector, which has strong anti interference ability and stable signal transmission.3. EXCELLENT PERFORMANCE: The transmitter is a wide voltage DC power input, with 2 independent analog outputs, and is suitable for 3 wire and 4 wire systems at the same time.4. ABS SHELL: The temperature and humidity transmitter is made of IP65 waterproof grade ABS material, and its shell is dust proof, oil proof and high temperature resistant.5. WIDE APPLICATION: This transmitter is widely used in agricultural greenhouses, flower planting and other situations that require temperature and humidity monitoring.Specification:Item Type: Temperature Humidity SensorMaterial: ABSDC Power Supply (Default): DC10-30VMaximum Power Consumption: 0.1WA Quasi Accuracy:Humidity: 2%RH (5%RH-95%RH, 25)Temperature: 0.4(25)B Quasi Accuracy:Humidity: 3% RH (5%RH-95% RH, 25)Temperature: 0.5(25)Default: -20-+60, 0%RH-95%RH without condensationTransmitter Circuit Operating Temperature and Humidity: -40-+120Default: -40-+80, 0%RH-100%RHProbe Working Temperature: 0.1Probe Working Humidity: 0.1%RHTemperature and Humidity Display Resolution: 1sTemperature and Humidity Refresh Time:Humidity: 1%RH/yTemperature: 0.1/yLong Term Stability:Humidity: 4s (1m/s wind speed)Temperature: 15s (1m/s wind speed)Protection Class: IP65.Package List:1 x Temperature Humidity Sensor6 x Screw2 x Expansion Screw4 x NutNote:1. The transmitter should be placed as vertically as possible to ensure that the sensor is below the transmitter when installed on the wall (the font on the transmitter is in the positive direction).2. The installation height is the sitting height of the person or the environmental area that mainly needs to be measured.3. Avoid installing it in an area that is easy to transfer heat, and directly generate a temperature difference with the measured area, otherwise the temperature and humidity measurement will be inaccurate.4. Install in a stable environment, avoid direct sunlight, keep away from windows, air conditioners, heating and other equipment, and avoid directly facing doors and windows.5. Try to stay away from high power interference equipment to avoid inaccurate measurements, such as inverters and motors.
