+
+This is a little project for our greenhouse. Even if we do not really need it (and I still need to make sure that the battery will be safe), this circuit uses a Raspberry Pi Pico for monitoring temperature, humidity, gas and and atmospheric pressure. The collected information is sent every 5 minutes to my Home Assistance instance via MQTT.
+
+The Pico is powered by a rechargeable battery connected to a repurposed solar panel from the garden, but the charger module can also be connected to a phone charger. However, as the Pico goes to deep sleep when it is not running, the energy consumption is very low.
+
+The shopping list, code and instructions can be found in my [electronics repository](https://github.com/mmartinortiz/electronics/tree/main/greenhouse).
