Hi I need help I would like to run 4pcs temperature sensors PT100 two-wire sensors are mounted in such a way that they can not be replaced with another sensor
For this purpose I bought 4pcs of MAX31865 boards
I would like to run these 4x PT100 sensors using MAX31865 and ESP8266 NodeMcu V3 CH340 in ESPHome program
I would like to run in the program ESPHome because I met him generally I’m a beginner when it comes to HA
So. What is the question?
It should work, as long as each device has a unique address.
Are they going to be in parallel or daisy-chained?
SPI devices are, by the way, five wire:
- CLK
- MOSI
- MISO
- Gnd
- 3V3
CLK - D2
MOSI- D1
MISO -D0
Gnd - Gnd
3V3-3v3
2/3 WIRE together solder, ie jumper 2 Wire together solder, ie jumper
Total gibberish.
Please draw a schematic.
