BBQueue is an open hardware, open source wireless temperature probe device for cooking.
Features:
- Low-power radio (RFM69): This can operate for weeks on battery power and has much better range than WIFI.
- Web-based dashboards: temperature trends are viewable in any web browser.
- High accuracy: Uses commercial temperature probes (e.g. thermoworks) and an ADS1115 analog-to-digial converter.
- Two temperature channels are available to monitor both food and bbq temperature.
- Battery level monitoring.
Hardware schematics are available here.
- The analog to digital converter tends to pick up noise when the power supply is plugged in. Better to run on batteries until I can figure this out and create a new hardware revision.
