Tableta con sensor de temperatura para Aduino, Raspberry pi 2, Domótica .. the module uses a single-bus digital temperature sensor DS18B20, the external power supply voltage Range is 3.0 V to 5.5 V, No standby power. Measurement temperature range of -55 ° C to +125 ℃, Fahrenheit equivalent 67 ° F to 257 ° F, -10 °C to +85 ° C range accuracy of ± 0.5 ° C. the temperature sensor is a programmable resolution of 9 to 12 temperature conversion to 12-bit digital format With a maximum of 750 milliseconds formula User definable nonvolatile temperature alarm settings. each DS18B20 contains a unique serial number, can be with a plurality ds18b20s Exists in a bus. Temperature sensor can be placed at different places in the detected temperature.
Cuidados y Notas Técnicas
The DS18B20 and ordinary transistors look similiar, so be careful not to regard it as a generalPass transistor to avoid damage.
- in order to prevent damage to the DS18B20 ensure that the powerLine and ground are not reversed.
- the relevant technical data on the bus did not mention a single number that can be linked to how much DS18B20, But in practical applications are not as many, and we should pay attention to.
- There is a bus length limitation that should be taken in consideration when long-distance communications, consider bus distributed capacitance and resistance.
- Identify DS18B20 Temperature Sensor Module power line, ground, and data Line, power line and ground points connect to the Arduino test board +5 V, GND, Data bus connect to the digital port.
