Function documentation

MeterHydros21::MeterHydros21(char SDI12address, int8_t powerPin, int8_t dataPin, uint8_t measurementsToAverage = 1)

Construct a new Meter Hydros 21 object.

Parameters
SDI12address The SDI-12 address of the Hydros 21; can be a char, char*, or int.
powerPin

The pin on the mcu controlling power to the Hydros 21. Use -1 if it is continuously powered.

  • The Hydros 21 requires a 3.5-12V power supply, which can be turned off between measurements
dataPin The pin on the mcu connected to the data line of the SDI-12 circuit.
measurementsToAverage The number of measurements to take and average before giving a "final" result from the sensor; optional with a default value of 1.

The SDI-12 address of the sensor, the Arduino pin controlling power on/off, and the Arduino pin sending and receiving data are required for the sensor constructor. Optionally, you can include a number of distinct readings to average. The data pin must be a pin that supports pin-change interrupts.

MeterHydros21::MeterHydros21(char* SDI12address, int8_t powerPin, int8_t dataPin, uint8_t measurementsToAverage = 1)
