The ESP32 Weather Station 3.0: an ESP32-P4 with a 10.1-inch display that measures temperature, humidity, particulate matter, CO2, VOC and NOX via the Sensirion SEN66. Plus battery-powered wireless sensors via ESP-NOW and LoRa, automatic display brightness and a weather forecast with three selectable APIs. Everything runs purely locally, without a cloud.

How can you control higher loads such as LED strips with the ESP32 when a single GPIO pin can only deliver a few milliamps at 3.3 V? In this article, I take a practical look at different transistor solutions for switching higher currents with the ESP32. I compare a Darlington transistor with three MOSFETs and show, which types are suitable for logic-level control.
