Arduino/ESP32 library for JXCT's RS485 based substrate NPK sensor (5 pronged version)
Take a look at the example in src/main.h to learn how to use it
- Arduino/ESP32
- UART TTL to RS485 converter. I'm using the MAX485
- JXCT 5 pronged NPK sensor
- The SoftwareSerial library by Peter Lerup and Dirk O. Kaar
- Can read: pH, TDS, temperature, moisture, conductivity, salinity, nitrogen, phosphorus, potassium
- CRC checking
- write directly to stream
- Asynchronous updates for multiple sensors on the same bus
- Changable addresses and baud rates
- Settable calibration values
