Keyestudio DS18b20 temperature detector probe adopts the brand-new 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℃.
Compared with other DS18B20 temperature detector sensors, ours has added a switching module, so just need to connect the G, V, S pin of module when test it, pretty easy and simple. If without this switching module, in testing, need to connect the signal end (yellow line) of sensor to the Digital port of microcontroller, meanwhile, also need to add a pull-up resistor on the Signal end, or else the test will fail.
