The PST THD Sensor is a cost-effective way to accurately measure the temperature, relative humidity and dewpoint. 

This information is then transmitted wirelessly, stored in a database, and viewed with iStatus Reporting software. 

The sensor data can be easily scaled to output in whatever engineering units are needed.
Features
  • This Wireless sensor Transmitter uses two AA batteries with an approximate twoyear battery life. 
  • These 900 MHz transmitter radios use the license-free 902-928 MHz ISM band. 
  • Data is typically transmitted once every 12 seconds to optimize battery life and minimize RF traffic. 
  • The transmitter range will vary depending on the location. 
  • Typical industrial environments are not ideal for RF reception; it is best to evaluate the site with a transmitter and software to find the ideal locations for transmitters and receivers.
