ESP32 multichannel DS18B20 temperature sensor in MicroPython by Bad_Driver



This ESP32 project can handle 7 DS18B20 sensors, it is easy to adjust the actual number of sensors in the python script and TC definition. The TC definition is very simple only containing the minimum to read the values.

Atmega328/Arduino with up to 8 TMP275 temperature sensors by oz2cpu

A Arduino sketch and hardware that can handle up to 8 temperature sensors.

Owon BT41T+ DMM

TC cannot directly support the Owon  B41T+ bluetooth multimeter, but somebody has made a a program for ESP32 to handle convert from Bluetooth to serial the interface: https://github.com/palmerr23/Owon_B41T



Sanwa PC7000 DMM &  Lutron DW-6063 power meter by  Kazimierz Król

A custom build serial interface and TC definition for the above two meters.

10 channel 12bit ADC module by WA



There is nothing DIY in this project, it is about a module with 10 ADC inputs, each can handle up to 3.3V, the controller is a STM32F103C8T6. It has build-in USB interface and can directly be connected to a computer and will deliver the data on a virtual serial port.
It can be used for many sensors and with a OpAmp and a low ohmic resistor for measuring DC current.

In TestController it is included as standard and called ADC10F103C.

It has many different names: Dolla Tek USB interface, Denash 10 Channel 12 Bit USB Interface, STM 32 USB Interface 12 Bit 10 CH, USB STM32 UART ADC Module 10-channel

It can be found on EBay, Aliexpress Amazon etc.



BME280 (Pressure, temperature & humidity) sensor by WA



This project uses ATMEGA328 processor to connect a BME280 sensor to TestController.

The zip file contains schematic, program for processor in IntelHex and TestController definition.



Brymen BM869s custom build serial interface

This interface is cheap and make it possible to use the meter on Linux and Mac.

There is also windows software for the BM869s included.
