ESP-8266 Experiments


esp-8266 esp-01s greenhouseIt’s over a year since I started this in late 2019.  A work in progress, experimenting with the ESP8266 D1 Mini-pro and the ESP-01S running Tasmota. 

Connecting to a Orange-Pi attached to the back of a 22″ LCD screen and running InfluxDB and Grafana.  This setup has been collecting data from a ESP-01S in the greenhouse and a D1 mini-pro in the computer cabinet.

The ESP-01S failed a few weeks back (late March 2021).  Not surprising as it was a temporary install hanging from the roof, powered by a 10W solar panel and 3-cell 18650 battery.  It lost the DHT11 sensor configuration and the sensor itself was providing bad data.  A tidy up and new sensor and it’s working but possibly not as reliably as it was.  Time to update it to the D1-mini-pro board.

wlc_1a controller esp-01With a couple of applications in mind I designed a carrier board for the D1-mini-pro to make it easier to use and operate from 12V.  If the D1-mini module is soldered directly rather than on header connectors the whole thing slides into a 32mm conduit for mounting outdoors and harsh environments.  A few more details Here
