A word about 12V power adapters

It is highly recommended to get a name brand power supply. A good quality 1A supply can drive a Raspberry Pi 3, Wifi, Servo Damper, and up to a 500mA blower without breaking a sweat. Generic no-name power supplies that can be found on Amazon or eBay might cost half as much but some 1A supplies aren't even capable of providing enough power to power up the Pi and HeaterMeter and will reboot endlessly, on servo movements, or when enabling the blower. In addition, these cheap supplies can lack the noise suppression circuitry which can affect HeaterMeter readings or protection components which can make them unsafe in fault conditions. If purchasing an generic supply it is recommended to use a 2A supply at a minimum to be confident that HeaterMeter will work at all.

HeaterMeter is an AVR / Arduino microcontroller-based automatic BBQ controller. Temperature data read from a standard thermistor (ThermoWorks, Maverick) or thermocouple probe is used to adjust the speed of a blower fan motor mounted to the BBQ grill to maintain a specific set temperature point (setpoint). A servo-operated damper may optionally be employed. Additional thermistor probes are used to monitor food and/or ambient temperatures, and these are displayed on a 16x2 LCD attached to the unit. Buttons or serial commands can be used to adjust configuration of the device including adjustment of the setpoint or manually regulating fan speeds.

The HeaterMeter board can optionally be mated to a Raspberry Pi (Model A, A+, B, B+, Zero, Zero W, Pi 2 and Pi 3) to provide web access. Web access provides live streaming updates, graphing, archives, and SMS/Email support for alarm notification. Android and iPhone apps are also available but not required, the website works on mobile devices as well (asterisk: it isn't a mobile site, but it does work).

HeaterMeter is a fully open source project in both hardware and software areas and is released under MIT license.
