Product description: Expansion module for connecting DS18B20 sensors - 1-Wire - STEMMA JST PH 2 mm - Adafruit 5971
A practical module from Adafruit designed to easily connect DS18B20 sensors in IoT projects. Thanks to the JST PH 3-pin connector and built-in screw connectors, you can quickly connect temperature sensors in TO92 packages or with wires . The module has a built-in 4.7 kΩ pull-up resistor (can be disconnected by cutting the track) and an LED indicating data transmission in the 1-Wire protocol. It offers compact dimensions (25.3 x 18 x 10.2 mm) and low weight (3.1 g). It will work perfectly in projects based on the Wippersnapper platform or microcontrollers with DS18B20 support. The kit does not include DS18B20 sensors , which allows for flexible adjustment of the solution to individual needs.
Expansion module for connecting DS18B20 sensors - 1-Wire - STEMMA JST PH 2 mm - Adafruit 5971.
The screw connector allows you to easily connect the DS18B20 sensor to the board.
Main features of the module
- Daisy chain connection of sensors: JST PH 3-pin connector enables quick creation of connections between modules
- Screw connections: easy connection of sensors in TO92 housings or with wires without the need for soldering
- 4.7kΩ Pull-up Resistor: Built-in resistor with cut-track disable option
- LED: shows 1-Wire data transmission activity
- Compact size: small dimensions and lightweight design
- Wippersnapper Compatibility: Designed to work with the Adafruit IoT platform
Module connection and pinout description
The module connects to DS18B20 sensors using screw connectors. Simply connect the power (VCC and GND) and data (1-Wire) wires . Thanks to the built-in pull-up resistor, no additional circuitry is required on the data line. If you need to adjust the configuration, the resistor can be deactivated by cutting a dedicated track on the board.
- V+ - power supply pin for the DS18B20 sensor
- Signal - 1-Wire line signal pin for the DS18B20 sensor
- GND - ground connection for the DS18B20 sensor
This plate does not include the DS18B20 sensor in the set. This is only an auxiliary module - adapter.
The sensor and JST PH compatible 3-pin cable must be purchased separately.
