Description:

Keyestudio 18b20 temperature detector probe adopts the brand-new original 18B20 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℃.
