Decagon5TM class

The Sensor sub-class for the Meter ECH2O soil moisture sensors.

These were formerly sold as the Decagon 5TM.

Base classes

class SDI12Sensors: The main class for SDI-12 Sensors.

Function documentation

Decagon5TM::Decagon5TM(char SDI12address, int8_t powerPin, int8_t dataPin, uint8_t measurementsToAverage = 1)

Construct a new Decagon 5TM object.

Parameters
SDI12address	The SDI-12 address of the ECH2O; can be a char, char*, or int.
powerPin	The pin on the mcu controlling power to the ECH2O Use -1 if it is continuously powered. The ECH2O 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.

Decagon5TM::Decagon5TM(char* SDI12address, int8_t powerPin, int8_t dataPin, uint8_t measurementsToAverage = 1)

Construct a new Decagon 5TM object.

Parameters
SDI12address	The SDI-12 address of the ECH2O; can be a char, char*, or int.
powerPin	The pin on the mcu controlling power to the ECH2O Use -1 if it is continuously powered. The ECH2O 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.

Decagon5TM::Decagon5TM(int SDI12address, int8_t powerPin, int8_t dataPin, uint8_t measurementsToAverage = 1)

Construct a new Decagon 5TM object.

Parameters
SDI12address	The SDI-12 address of the ECH2O; can be a char, char*, or int.
powerPin	The pin on the mcu controlling power to the ECH2O Use -1 if it is continuously powered. The ECH2O 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.

bool Decagon5TM::getResults(void) override

Gets the results of either a standard or a concurrent measurement.

Returns	bool True if the full number of expected results was returned.
