Product Information
The Sentinel Temperature, Relative Humidity and CO2 Controller eliminates guesswork while it controls indoor garden environments with accuracy, and this upgraded version is even better than the original! It uses an even more accurate CO2 sensor, a more powerful CPU, a removable remote probe assembly, a moisture-resistant housing, and plant-friendly green LED function lights. Its combination CO2 & light level sensor is housed in a separate remote sensor enclosure that can be located up to 100 ft from the controller. It features an easy-to-read LED display and simple buttons to enter the desired PPM settings and display the current PPM reading. It can also be connected to other controllers so that the CO2 is disabled, and it can be operated in Fuzzy-Logic mode (for compressed CO2), or ON-OFF (for CO2 generators). It also has the ability to control 3 other devices, a cooling device, a heating device and humidity device.
