Wemos D1 Mini + SHT30 shield enclosure

thingiverse

This is a simple enclosure designed to hold a Wemos D1 Mini and the Wemos SHT30 Temperature/Humidity sensor shield securely in place.\r\n\r\nThe small baffle that comes with it effectively holds the shield to the base, reducing heat soak from the rest of the PCB slightly. Make sure to position it so that the 'tongue' of the shield is fully exposed in free air.\r\n\r\nEven with the baffle and holes in the top, the heat generated by the ESP8266 and the LDO on the Wemos will still cause inaccurate temperature readings. To overcome this issue, use deep sleep mode. For the D1 Mini to wake up from deep sleep, simply solder a small piece of wire between D0 and RST on the top of the board.\r\n\r\nI personally use Tasmota on my units and once you have confirmed they are working properly, enable deep sleep by entering two specific commands in the Tasmota console...\r\n\r\nTelePeriod 10\r\nDeepSleepTime 300\r\n\r\nThese commands mean that it sends readings 10 seconds after waking up and then goes to sleep for 300 seconds. You can adjust these settings slightly as needed, but keep in mind that you need a short TelePeriod to control how long the device stays awake. Only enter these commands once you are satisfied with your Tasmota configuration, as changing them later may prove difficult.
