Keyestudio 18B20 Waterproof Temperature Sensor + 4.7K Resistor (3PCS)
Description
This kit includes three DS18b20 temperature detector sensor and three 4.7 K resistors.
Keyestudio DS18b20 temperature detector probe adopts the brand-new and original DS18B20 temperature sensor chip. Each pin of chip is separated by heat shrinking tube to prevent the short circuit, and sealed inside for waterproof and damp-proof. Its direct "One line Bus" digital transmission greatly improves the anti-jamming capability of system, suitable for field temperature measurement in harsh environments.
At the same time, it is sealed with a high thermal conductivity of sealing rubber strip, to ensure the temperature sensor’s high sensitivity, with a very tiny temperature delay. Its measured temperature range is from -55℃ to +125℃, in the range of -10℃~ +85℃, its accuracy is±0.5℃.
When testing it, need to connect the signal end (yellow line) of sensor to the Digital port of microcontroller, meanwhile, need to add a pull-up resistor on the Signal end, or else the test will fail. This kit we provide three 4.7 K resistors to used as pull-up resistor.
Specifications
- 1.Each pin of chip is separated by heat shrinking tube to prevent the short-circuit
- 2.Sealed with premium stainless steel tube for waterproof, damp-proof and rustproof.
- 3.Total length of 1m
- 4.3.3-5V power supply
- 5.9~12 bit adjustable resolution
- 6.Temperature sensing range: -55℃~+125℃(lead wire can bear the temperature up to 85℃)

Example Result
After wiring, powered up, upload the above code to the board, then open the serial monitor and set the baud rate as 9600. Eventually, you should see the temperature value in current ambient. Shown below.
