Can anybody help me , i need help with connecting and coding the arduino chip with the ESP32 internet ship and Zhed Soil PH Meter, 7 in 1 i’ll put a photo of the sensor and other components
if you do a web search for esp32 Zhed Soil PH Meter you will get a number of links which should help
Be aware that this device is a scam, it is impossible for it to measure NPK.
We had another problem when we had to connect between the sensor and the wire connecter it seem it doesn’t fit
Searched and found nothing
Remove "Zhed"
NPK Soil Sensor (mini)
A connected to RS-485 Module (A)
B connected to RS-485 Module (B)
VCC connected to common VCC
GND connected to common ground
It is not a problem, cut the original connector and solder what you want. It won't affects the "quality" of the sensor data
I dont get it , how and which one
And how do i connect them
With short wiring. Exactly, depends on the specific model of the converter. Do you have one already?
you mean the RS485 - ttl ? We planning to buy it
Cause we were thinking that if we don’t need the internet chip do we need the RS485 -TTL ? I saw a lot of wiring and they used it
And one of my team suggested that we change the arduino chip to arduino r4 wifi and have some questions if it will change anything from wiring to coding
You still need converter, either RS485-TTL for "arduino"(ESP32) or RS485-USB if you want to connect your sensor to computer.
Yes, it will. I personally prefer Esp32.
