Which combination of devices will let me monitor temperature/humidty remotely over Wifi using Qwiic?

Qwiic System

Please also suggest me a battery and an enclosure if those are also available.

Very anxious to try and replicate a product that costs us many hundreds of dollars per unit and $20/year in cloud fees.

I know battery life may not be the greatest, but that’s OK as long as the batteries are affordable or rechargeable.

Thanks so much! :mrgreen:

So far I’m thinking these two things plus a battery and some connectors is all I need right?

Can I power this all with USB power bank? Or does it need to be a LiPo pack type thing?

You’ll need an 2.4GHz antenna too but those should all work.

power bank or a lipo would be fine for power but a lipo would be more energy efficient.

Thank you for the reply.

How would I charge the LiPo pack once it’s dead and will I be able to have the ESP32 tell me when the battery is getting low? I presume there is some kind of script I can write to monitor battery levels?

If you read the directions, there’s a battery charger built into the ESP32 thing plus. There isn’t a way to monitor battery charge though so you’d need to build an external circuit for that or use something like the [lipo fuel gauge.](SparkFun LiPo Fuel Gauge - TOL-20680 - SparkFun Electronics)
