The W1209 is an incredibly low cost yet highly functional thermostat controller. With this module, you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
Features:
• The W1209 thermostat module controller has a sensor input, keys, LED display, and a relay. It can be reprogrammed for control, timing, or counting.
• Temperature Measurement Range: -50~110℃. Control Precision: 0.1 celsius.Input Power (DC): 12V; Measuring Inputs: NTC (10K 0.5%) ; Waterproof Sensor: 0.5M; Output: 1 Channel Relay Output, Capacity: 10A; Power Consumption: Static Current: 35mA; Current: 65mA.
• Electronic digital thermostat with a 3-digit LED display, extremely bright. Operation both in heating and cooling to easily control equipment and devices.
• The output is electronically controlled by a microprocessor, to guarantee the utmost precision of intervention and an excellent resolution of reading temperature.
• The NTC probe is waterproof and allows to control the temperature even of fluids, allowing the controlled heated or cooling【Note: The wood laminate case is the clear plastic case. You need to tear the wood outside layer off carefully, the outside layer is very thin. (It can protect the inside to prevent scratches.) And you need to assemble and install the case by yourself, it comes disassembled with tiny bolts and nuts.)】.
