- *Multiple temperature sensors (0-500C thermocouples) and would include two of the sensors - Would be able to have more temperature sensors via a prototype area on the PCB
*Two thermistors for indoor and outdoor temperature readings (or wherever you put the sensors)
*Backlit LCD display
*WiFi connectivity for monitoring
*The ability to set 'safe ranges' for each sensor and would send an email and/or sound audible noise if an alarm was triggered
*Web page for viewing current values, historic graph of previous values (real time clock used to track date/time), exportation of historic data, and configuration
*Low voltage outputs for controlling external devices based on sensor values(IE a power transistor to turn on/off a relay for a fan/blower/stove shutdown) - This would be on a prototype area on the PCB for the end user to develop the circuit
*Inputs for external contact closures - This would be an option for the user to wire on the Prototype area. If there is enough interest in this may pre-wire 1-2 inputs for this
A few features that have been requested but I haven't figured out yet...
- *Monitoring coal level in hopper - I don't have a hopper so don't really have too much of an idea on the best way to sense the level. Possibly distance finding with ultrasound?
*Draft monitoring - The sensors to work in the range we need with the accuracy required look to be prohibitively expensive and would probably have issue with flue gasses degrading the sensor over time. Another option would be to use a typical dwyer water filled manometer with sensors to read the water level, probably wouldn't look all that great but could be done for reasonably low costs and would eliminate the flue gas issue Waiting to hear back on pricing on a sensor. If pricing is reasonable it is in a package that would be suitable as an add-on module.
Does anyone have any interest in such a device?
Does anyone have any suggestions for any other features or how to implement anything?
This is just in the planning stages in my head at this point but will most likely be making one for myself regardless, falls into the cool stuff that I want to build category. I'll keep this post updated as people make suggestions and feedback.
