SenseTemp: improved temperature sensing in an Adafruit Feather form factor #Feather #FeatherWing #OHSW #Adafruit @osterwood @crowd_supply

SenseTemp: Level-up your temperature sensing

Via Twitter and Crowd Supply: SenseTemp is an open source, four-channel temperature sensor designed for instrumenting electronics. It uses extremely accurate platinum resistive temperature detector (RTD) elements which are small enough to place directly on ICs, heatsinks, and other points of interest on an electronic circuit board.

SenseTemp Use Cases

  • Measure regulator, processor, motor, and IC temperatures on your PCB, product, or autonomous robot.
  • Understand thermal conduction from your application processor to the ambient environment.
  • Measure heat-loss of windows in your home

Compatible with Adafruit Feather

SenseTemp can be operated by many different Adafruit Feather-compatible boards, including:

Feather Host Supported Language Wireless Code Update
Adafruit M4 CircuitPython Native USB disk
Adafruit M0 LoRa CircuitPython LoRa Native USB disk
Adafruit ESP32 MicroPython Wi-Fi / BLE via USB serial port

Additionally, the Adafruit Feather M0 Adalogger, M0 Express, and HalloWing have also been verified to work with SenseTemp. The Huzzah ESP8266 is known to be incompatible due to limited IO on that processor. All other Feather hosts are likely hardware compatible. Software libraries for the MAX31865 are available for the Arduino IDE, CircuitPython, and MicroPython.

The M0 and M4 Feathers support USB natively, expose a serial endpoint, and mount on your computer as an attached mass storage device. This makes modifying the CircuitPython code very straightforward – you merely edit the files and save them. Example CircuitPython scripts are available in the SenseTemp repository.

Unfortunately, CircuitPython is not available for the ESP32 processor. To use an ESP32 host, MicroPython must be used instead. The SenseTemp repository has example MicroPython scripts and MicroPython libraries for the MAX31865 ICs. The ESP32 PCB has a serial-to-USB bridge IC which exposes a serial endpoint, but no virtual hard drive. To update code on the processor, we recommend using Adafruit Ampy, which streams file contents via that serial connection.

In either case, the Feather’s serial connection can be used to stream SenseTemp data to the attached computer or to interact with it via the REPL console.
