ICT’s IMS range of integrated weather sensors feature SDI-12 communications, ultra-low power operations, research grade sensing technology and an industrial grade protective casing and are designed for long term, maintenance free field operations. The IMS305 measures temperature, relative humidity, pressure, noise, wind speed, wind direction, PM2.5 and PM10 within a ventilated radiation shield.
ICT’s IMS series is fully supported by our range of IoT Nodes, providing flexible logging and connectivity solutions to suit any application.
