Description
Overview
GAOTek outdoor air quality tester supports analog sensors with 4 mA to 20 mA or 0 VDC to 5 VDC input. Micro-controller supports sleep mode for years long operation in battery. It provides on board voltage output 12 or 24VDC for external analog sensors in different applications e.g. soil humidity sensor for agriculture.Stabilize external analog sensors reading before capturing data.One base station will accept signal from all wireless sensors (temperature, humidity, analog sensors, digital alarm) together forming a total solution.It connects directly to any industrial sensors in the market. Wireless Load Cell, Wireless Pressure Sensor, Wireless Level Sensor, Wireless Weather Station, Wireless Wind Direction Speed Sensor, Wireless Analog Temperature Sensor, Wireless PM2 Air Quality Sensor.
