PID Temp Humidity Controller with Logging IM3504

Ajinkya Electronic Systems manufactures Micro controller based temperature humidity controllers using latest technology. These controllers are used for combined control of temperature and humidity. Controller is available with PID control algorithm and can be configured on site. These controllers can be directly interfaced to accept input from different types of humidity sensors as well as RTD sensor for dry bulb / wet bulb. It has facility to Data Logging and monitoring. Logged data can be viewed on PC with the help of software.


*Microcontroller based Digital Circuitry
