DS18B20 Waterproof Temperature Sensor DIY Smart Home Sonoff Arduino Raspberry

Article description DS18B20:

DS18B20 temperature sensor in various versions

Available as either a probe or a single sensor.

The probe uses a new DS18B20 temperature sensor chip. Each pin of the chip is separated by a shrink tube to prevent short circuits. This version is waterproof and suitable for any indoor or outdoor use.

Suitable for your Arduino or Raspberry Pi projects. Also very suitable for Sonoff Smart Switches. Among other things, for Sonoff TH10 / TH16 with 2.5mm jack connection, or e.g. Sonoff Basic via GPIO, Shelly and Shelly Plus series with Temp Addon, etc.

The resolution can be adjusted from 9-12 bits to optimize speed or accuracy. Wide temperature range -55 °C - 125 °C

Note:

For operation on Raspberry Pi or Arduino, a 4.7 kOhm resistor or a suitable adapter shield is always required.

1 Wire Adapter Shield for DS18B20

Suitable adapter to connect the DS18B20 sensor to Raspberry Pi or Arduino. Without complicated soldering or working with breadboards.

Ready configured with resistors, LED diode and the appropriate PIN connections.

Also suitable for other 1 Wire sensors or components.
