Need to automatically control the temperature (and humidity) of something? This digital controller can do it. The model is 3028. It has a clear digital screen that shows both the current temperature and humidity, as well as your set points. The temperature control range is wide: from -20°C all the way up to 80°C. It works with standard household voltage (110-240V AC, but make sure you get the correct voltage option). It's built into a compact, ABS flame-retardant plastic case that measures about 3 x 1.4 x 3.3 inches. The sensor is built-in (integrated), so you don't have a separate probe to worry about. It's very low power (under 3W). Accuracy is decent at ±1°C for temperature. You'd use this for projects like controlling a DIY incubator for eggs, a seedling heat mat, a reptile tank heater, a fermentation chamber, a small greenhouse, or a drying box. Installation requires wiring it into your power circuit for the heater or cooling device you want to control, so some electrical knowledge is needed. It's a simple, affordable tool for hobbyists and DIYers who need precise environmental control.
