This ESP01 driven station collects data from a BME280 (air pressure, humidity and temperature) and a MAX44009 (light). It transmits its data over the WIFI at 15 minutes intervals. The weather station is running outside again (16/4/21). It now runs on one 18650 rechargeable battery. Note – temperature recording is highly inaccurate during daytime. The case for the station has a perspex cover. When the sun comes out it becomes a mini-greenhouse.


Battery voltage = 3.4 V
