HeaterMeter is a system for monitoring or control of BBQ smokers and grills in both standalone and Raspberry Pi integrated web-based automation.

HeaterMeter Kit

• HeaterMeter v4.2.4 PCB (Purple Circuit Board)
• All parts from the Mouser project
• All parts from Digikey (6.2CFM Blower, Pi header, and Probe connectors)
• Current LCD color: Yellow/Green

Does not include: Raspberry Pi, SD Card, Wifi Adapter, 12V power supply, Probes, Case/Enclosure

HeaterMeter Kit w/Thermocouple PCB

• HeaterMeter Kit
• Surface mount components needed for thermocouple support (AD8495) for pit probe already soldered and tested.
• Through-hole thermocouple plug (PCC-SMP-K) included but is not soldered, as it makes assembling the rest of the board a little easier without it in place.

For just the Thermocouple PCB only, see HeaterMeter v4.2 Thermocouple PCB.

Support

Be aware all products are sold without warranty or technical support. I do guarantee that the thermocouple amplifier is operational before shipment, however due to the DIY nature of the kit and varying levels of soldering and assembly expertise, I can not provide replacement parts for possibly non-functional components. All assembly support questions should be directed to the tvwbb.com forums and I will not diagnose hardware problems via email.

About HeaterMeter

HeaterMeter (HM) is an AVR / Arduino microcontroller-based automatic BBQ controller. Temperature data read from a standard "Maverick" thermistor 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 probes are used to monitor food and 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 or B, not B+) 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.

International Orders

I do ship internationally to Canada or European Union countries. However, because parcels must be hand-accepted at the post office I only ship about twice per week. Expect about weeks for delivery, most of the time showing up as in Miami.
