Detailed Description

Deprecated:: This class is being replaced by the upm-temperature library and the Temperature class.

ID: grovetemp
Name: Temperature Sensor
Category: temp
Manufacturer: seeed
Connection: analog
Kit: gsk

Basic UPM module for the Grove temperature sensor on analog. This sensor uses a thermistor to measure ambient temperature. The conversion formula has been updated to work with versions 1.1 and 1.2 of the sensor. For the older v1.0 sensor you will have to specify R0 and B values when initializing the device. The range of this sensor is -40 to 125 C and accuracy is +/- 1.5 C.

    // Create the temperature sensor object using AIO pin 0
    upm::GroveTemp temp(0);
    std::cout << temp.name() << std::endl;
    // Read the temperature ten times, printing both the Celsius and
    // equivalent Fahrenheit temperature, waiting one second between readings
    for (int i = 0; i < 10; i++) {
        int celsius = temp.value();
        int fahrenheit = (int) (celsius * 9.0 / 5.0 + 32.0);
        printf("%d degrees Celsius, or %d degrees Fahrenheit\n", celsius, fahrenheit);
        upm_delay(1);
    }
    // Delete the temperature sensor object

Grove analog temperature sensor constructor

Parameters

pin	Analog pin to use
scale	Scaling factor for raw analog value from the ADC, useful for mixed 3.3V/5V boards, default 1.0
r0	zero power resistance, this is 100K (default) for v1.1-v1.2 and 10K for v1.0 of the sensor
b	thermistor nominal B constant, this is 4275 (default) for v1.1-v1.2 and 3975 for v1.0 of the sensor
