KY-028 Digital Temperature Sensor Module For Arduino

KY-028 Digital Temperature Sensor Module

The simple circuit of KY-028 Digital Temperature Sensor Module and integrated LED connecting to digital 13 interfaces to make temperature indicator light. Use number 13 interface to connect the integrated LED, connect a digital temperature sensor to the number 3 interface. When the digital temperature sensor senses key signal, the LED is on, otherwise, its out.

Features:

• Using the NTC thermistor sensor,
• Good sensitivity
• the comparator output signal clean waveform is good, driving ability than 15mA.
• the output format: Digital switching output (0 and 1)
• Power supply: 3 – 5V
