DS18B20 Waterproof Temperature Sensor is a digital sensor which can reach the digital data resolution up to 12 bits and has ±0.5°C accuracy from -10°C to +85°C. It includes an analog-to-digital converter to convert the analog signal to the digital output with the resolution up to 12 bits.

Dependencies

This driver depends on:

• grove.py

This is easy to install with the following command.

pip3 install Seeed-grove.py

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

    DS18B20 = seeed_ds18b20.grove_ds18b20()
    print("Please use Ctrl C to quit")
    while True:
        temp_c,temp_f = DS18B20.read_temp
        print('temp_c %.2f C   temp_f %.2f F' % (temp_c,temp_f),end=" ")
        print('\r', end='')
        time.sleep(0.5)

if __name__ == "__main__":
    main()
