Note: If you want to place the bulk order that the stock is not enough, please contact with us.
The module (Digital Temperature Sensor) is based on the digital temperature sensor module DS18B20 single bus.
Due to a single bus interface allows multiple DS18B20 mounted on the same bus, and the on-board interface to facilitate multi-point temperature, the use of multiple digital temperature sensor module can achieve a signal line measuring a large area multi-point temperature.
Pullup resistor on the board can be directly connected to most microcontroller, the measured temperature range of -55 ~ +125 , the accuracy of which is in the range of -10 ~ +85 ± 0.5 , widely used in buildings, equipment , machinery, greenhouses and other temperature measurement and control.
Features
1 On-board switch can be set on a pull-up resistor is connected, multi-point temperature measurement applications, usually as long as a pull-up resistor to pull-up resistor should be disconnected on the remaining temperature measurement module.
2 single bus communication, multiple modules can share a data cable
3. Supply voltage of 3.3 ~ 5.5V
4. Thermometer resolution procedures available to select from 9 to 12, the higher the resolution, the longer the temperature conversion time
5.4 M2 screw positioning holes for easy installation
Interface
Control Interface: A total of three pins (GND, VCC, SIG), GND to ground, VCC is the power supply, SIG is a single-bus communications signal pin;
Bus common interface: a cascade of similar usage for multi-point temperature, without the need for each group of lines are connected to the main control board.
Switch: If you are a single point temperature, it should be appropriated PULL-UP end of the handle, pull-up resistor connected to the 4.7K; If it is multi-point temperature measurement, temperature measurement module is more than just a pull-up resistor module the rest are appropriated for the other side.
Temperature sensors: 2013 + of DS18B20, single-bus digital temperature sensor;
Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination;
