Features: High sensitive water temperature sensor, small temperature delay. The well sealed sensor probe is waterproof. Designed with pluggable terminal adapter so that temperature sensor could connect to a pull-up resistor to use. Pluggable terminal adapter digital port adds pull up resistor, using jumper cap to switch, so the sensor can connect to microcontroller directly. It can be widely used in many projects such as soil temperature detection, hot water tank temperature control, etc. Specifications: Power Supply Voltage: 3.0V~5.5V Resolution: 9~12bit(adjustable) Temperature Display Range: -10 to +85(error 0.5) Operating Temperature Range: -55 to 125 (85 maximum for wire) Wiring: Green(DATA); Red(VCC); Yellow(GND) Package Includes: 1 x Module 1 x Probe 1 x Adapter Wire Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
