Powered by 12V DC, it offers precise temperature regulation with easy configuration via three switches and real-time LED display feedback. Ideal for managing electrical devices with temperature-sensitive needs, it supports loads up to 240V AC/5A or 14V DC/10A, making it a versatile choice for professionals seeking efficient, plug-and-play thermal management. ## Description W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. It is an affordable, thermostat controller. Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it. NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module. Review: It's a reliable temperature sensor and relay assembly - It seems to be a reliable sensor, I have been using it as a cooling solution for 12v FTTH modem, have set the max temperature at 35, after which the fan gets switched on and starts cooling the modem. It usually switches on an off once is 5 minutes. Now I have been using it for more than 2 months, it is still going on strong Review: Need Good User Manual - Product god but the user manual is not good need brief description for setup the device. ## Features - W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. - W1209 NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. - NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. - W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. - The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08JYHR93V | | Are batteries included? | No | | Best Sellers Rank | #50,217 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #280 in Temperature Controllers | | Brand | Robocraze | | Colour | black,green | | Country of Origin | China | | Customer Reviews | 3.8 3.8 out of 5 stars (33) | | Date First Available | 24 September 2020 | | Generic Name | W1209 Thermostat | | Item Dimensions LxWxH | 22 x 52 x 91 Millimeters | | Item Height | 9.1 Centimeters | | Item Weight | 15 g | | Item Width | 5.2 Centimeters | | Item model number | LD-W3BR-M7LJ | | Manufacturer | 9th Main, 1st C Cross, HRBR Layout, Banaswadi, Bengaluru, Karnataka 560043, 080 4851 1516, Robocraze | | Model number | LD-W3BR-M7LJ | | Number of Memory Sticks | 1 | | Packer | 8123057137 | | Product Dimensions | 2.2 x 5.2 x 9.1 cm; 15 g | | Voltage | 12 Volts | ## Images ![Robocraze W1209 Digital Thermostat Temperature Controller Module DC 12V with NTC Sensor, Relay & LED Display (-50°C to 100°C) - Image 1](https://m.media-amazon.com/images/I/614ly-0macL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a reliable temperature sensor and relay assembly *by A***V on 6 March 2021* It seems to be a reliable sensor, I have been using it as a cooling solution for 12v FTTH modem, have set the max temperature at 35, after which the fan gets switched on and starts cooling the modem.
