Temperature sensor (digital thermometer) DS18B20 sealed IP67 Arduino, cable 1 meter Отзыв

Wired digital temperature sensor in a metal sleeve, model DS18B20 Digital temperature sensor in a metal sleeve. Designed to measure the temperature of the heat carrier of the heating system. Protected from moisture. Does not require calibration. Wire length 1 m. Measuring temperature range: -55 - +125°C Features of connecting and using a wired digital temperature sensor DS18B20 Connected in a loop in parallel. In total, you can connect up to 10 pieces; The distance of the last sensor in the loop cannot exceed 100 m; The maximum allowable distance of the sensor from the loop is 0.7 m; The minimum allowable distance between the connection points of the sensors in the loop is 0.2m; You can not connect sensors to one point; It is impossible to lay a loop with sensors in the same cable channel (or in close proximity) with the electrical wiring of the room; Sensors are susceptible to interference caused by faulty fluorescent and LED fixtures. Connection of temperature sensor DS18B20 It is necessary to connect the black and red wires together and connect them to the negative wire of the loop, and the yellow wire is connected to the signal (positive) wire of the loop
