Sensor Datasheet

Sensor Constructor

YosemitechY513::YosemitechY513(byte modbusAddress, Stream* stream, int8_t powerPin, int8_t powerPin2 = -1, int8_t enablePin = -1, uint8_t measurementsToAverage = 1)

Construct a new Yosemitech Y513 object.

Parameters
modbusAddress The modbus address of the sensor.
stream An Arduino data stream for modbus communication. See notes for more information on what streams can be used.
powerPin The pin on the mcu controlling power to the Y513. Use -1 if it is continuously powered.
powerPin2 The pin on the mcu controlling power to the RS485 adapter, if it is different from that used to power the sensor. Use -1 or omit if not applicable.
enablePin The pin on the mcu controlling the direction enable on the RS485 adapter, if necessary; use -1 or omit if not applicable.
measurementsToAverage The number of measurements to take and average before giving a "final" result from the sensor; optional with a default value of 1.

Sensor Timing

The sensor timing for a Yosemitch Y513

#define Y513_WARM_UP_TIME_MS = 1300
