This is how I modified a standard 100 Cigar humidor to provide constant humidity and temperature via WiFi. The pi part of the project could easily be adapted for any other use that requires a temperature and humidity sensor.
Features:
• Total cost around 125$ including 55$ for the unmodified humidor. You could do this cheaper
• Web interface providing temperature and humidity reading
• RESTful API to provide readings to other systems. (Screenshot above shows my ElasticSearch Kibana data feed)
• Configurable push alerts for temperature / humidity limits with both “warning” and “alert” levels.
• Push alert on open / closed lid (Know if someone is pilfering your cigars!)
• Buzzer on humidity or temperature outside of alert limits / clear buzzing with button.
