**SenseTemp is available on [CrowdSupply](https://www.crowdsupply.com/capable-robot-components/sensetemp) & [Mouser](https://www.mouser.com/Search/Refine?Keyword=sensetemp). Please visit the [campaign page](https://www.crowdsupply.com/capable-robot-components/sensetemp) or [Mouser](https://www.mouser.com/ProductDetail/Crowd-Supply/cs-sensetemp-01?qs=sGAEpiMZZMsSgQ5oX0A7uhzs7btMGoRQjdDbb5Xc%2F1l7fRq91ffQkQ%3D%3D) for product information and to purchase SenseTemp.**
SenseTemp provides four highly accurate and flexible temperature sensors which allow you to understand the operation of your:
* Mobile robot
* Embedded system
* Double pane windows on your house
* Home brewing operation
* Or any other system where temperature and thermal conduction is important
It's designed for quick tests as well as long-duration process monitoring.
## SenseTemp Features
* **Small:** so that it can be on a mobile system being tested. The RTDs themselves are 2 mm x 4 mm, making them thermally responsive and great for measurement of point heat sources
* **Inexpensive:** allowing many points of temperature monitoring
* **Battery Powered:** including LiPoly & USB power banks
* **Wireless:** to make test setup faster and more flexible
* **Open Software:** so that the device can directly feed data into a data logging system of your choice
* **Open Hardware:** to enable derivative designs and for easy hacking
## Specifications
|Feature|Specification|
|----|----|
|Sensors|4x Platinum resistance temperature detectors (RTDs)|
|RTD Accuracy|±0.15°C|
|Temperature Range|-50°C to 260°C|
|Interface ICs|4x [MAX31865](https://www.maximintegrated.com/en/products/sensors/MAX31865.html) with 4 wire sensing|
|Form Factor|[Adafruit Feather](https://www.adafruit.com/feather)|
|Dimensions|0.9" x 2.4"|
## Feather Hosts
SenseTemp is designed to mate with Adafruit Feather-compatible host modules, like:
* [Adafruit Feather M4 Express](https://www.adafruit.com/product/3857)
* [Adafruit Feather M0 Express](https://www.adafruit.com/product/3403)
* [Adafruit ESP32 Feather Host](https://www.adafruit.com/product/3405)
* [Adafruit HalloWing](https://www.adafruit.com/product/3900)
Note that the ES8266 Feather is **NOT** supported due to the limited IO on the ESP8266. It does not have enough pins to support the four SPI devices of the SenseTemp.
## Software
The software running on the Feather host processor does change based on the feather host you are using. This repository contains software for:
* [**CircuitPython:**](software-circuitpython) if you are using a Cortex M4 or M0 Feather.
* [**MicroPython:**](software-micropython) if you are using an ESP32 Feather. The ESP32 is not currently supported by CircuitPython.
## Hardware Revisions
* [CREAES](revisions/CREAES) : Last release 2018-10-18.
* Changed from 0805 to 0603 passive components.
* Moved all components to top side of PCB.
* Changed license from **CC BY-SA 4.0** to **CERN OHL v1.2**.
* Can be powered from either USB or Li-Ion sources.
* [X9EG](revisions/X9EG) : Released 2018-08-28.
* Added `SIO` pin with AT21CS01 1-Wire EEPROM for configuration & serialization.
* Added `EN` pin to allow host PCB to disable 5v to 3v regulator on this PCB.
* Changed RTD connector from 20 pin (used on XTMT version) to 16 pin.
* [XTMT](revisions/XTMT) : Initial version released 2018-05-18.
