KY-001 Temperature Sensor Specifications

  1. The module uses a single-bus digital temperature sensor DS18B20, the external power supply voltage Range is 3.0 V to 5.5 V, No standby power. Measurement temperature range of -55 ° C to +125 , Fahrenheit equivalent 67 ° F to 257 ° F, -10 °C to +85 ° C range accuracy of ± 0.5 ° C.
  2. The temperature sensor is a programmable resolution of 9 to 12 temperature conversion to 12-bit digital format With a maximum of 750 milliseconds formula User definable nonvolatile temperature alarm settings.

Required Hardware Devices

  • Arduino controller × 1
  • KY-001 Temperature Sensor Module × 1
  • USB data cable × 1
  • download and install the OneWire libary

Connecting

  • Pin – = connect to Arduino GND
  • Pin (middel) = connect to arduino +5V
  • Pin S = Signal, in this example connect to Arduino Digital port 10

When everything is properly connected, there is a led on the module that blinks when the sensor is read.
