with reference to the:
MODBUS-RTU RS485 Soil Temperature, Humidity and pH Monitoring Sensor (IP68, 5-30V).. limitations? could i use arduino with short burst pH measurements to reduce power consumption.
The connection of TTL->RS485 module should be RX to D1, TX to D0.
The RX and TX at both ends of the TTL serial port are opposite. Also you need to make sure your serial monitor baud rate is 9600
Tonny12138 Let me clarify. The problem will have to be portable in the field, in order to allow multiple samples.
Therefore the Arduino ESP32 (3.3V) will be battery operated and hence I will require low power consumption (plan to use 2 x 3.7V 5000mAH with a 3.7V to 5V converter). The Arduino will also be WiFi enabled.
Thank you.
Tonny12138 what is the accuracy of th pH measurement (low EC).
also the humidity is volumetric and if so what is the volume/area of measurement around sensor.
