Substrate-Sensor-RS485

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

Requirements

• 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

Features

• Can read: pH, TDS, temperature, moisture, conductivity, salinity, nitrogen, phosphorus, potassium
• CRC checking
• write directly to stream

TODO

• Asynchronous updates for multiple sensors on the same bus
• Changable addresses and baud rates
• Settable calibration values
