Sentinel has taken digital accuracy and combined it with ease of use. Our one-touch functions make using our products so easy, reading the manual may not be necessary. (although we still recommend it). No complex sub menus that are confusing and time consuming to navigate through. Many of our products serve more than one function (such as a heating or cooling control) making them extremely flexible and capable of being used in many situations. All Sentinel products were designed to maintain a very high degree of reliability while performing critical functions.

Controllers are automated devices designed to monitor the conditions inside your growing area 24 hours a day, and make adjustments as required to keep the area at your desire temperature, humidity and CO2 levels. Maintaining the environmental conditions in your growing area is crucial for success. We at Sentinel understand this and have designed our products to make this easy.

Sentinel offers innovative designs that are so unique, they are in a class all their own. There is simply no other products that have the capabilities, ease, and reliability Sentinel does. Sentinel Products are built for years of use, with heavy-duty components, re-settable circuit breakers for extra safety, easy to read LED displays, simple to use pushbuttons and comes with a 3 year warranty.
