CSI CS215 Temperature and Relative Humidity Sensor
CSI CS215 Temperature and Relative Humidity Sensor
Product details
CS215 is a probe developed by Campbell Scientific Inc. (CSI) based on the SHT75 probe from Sensirion, Switzerland, using CMOSens ® Temperature and humidity sensors manufactured with digital humidity and temperature probes for technology. This type of probe has demonstrated good reliability and excellent accuracy in over two years of testing in extreme high-altitude environments in the Alps.
The sensor adopts SDI-12 signal output, with simple programming, low power consumption, and good compatibility with CSI's CR series data collectors.
