PVC Spy V-1

I designed this module to fit inside a common 1.5-inch PVC pipe to keep sensors dry when deployed in austere environs.  You just gotta go buy the PVC and seal one end with a fixed cap and another end with a threaded cap and you can access your sensor payload whenever you want to charge and keep it dry. You can fit an 18650 battery on either side of the module or both depending on your needs.  I have tested this build by tossing it into my pool with an ESP32 C3, 18650, charge controller and temp sensor to monitor my pool temp in Home Assistant OS. No leaks if you do your PVC work correctly. There are other applications for this module as well. You can install a camera to take snaps on movement using LD2410C mmw sensor.  Paint the PVC to look like a log and clandestinely monitor your area.  Possibilities are endless and you get the durabiity of PVC along with this module. Plenty of holes to run wires as needed to either side and top and bottom. Designed for versatility.  Rotate it to fit your printing needs.
