The Pi can sink up to 16mA per pin if configured properly. Try that and see what happens. I normally order a few of each sensor so I can try with a different sensor if something is acting up, though.

#raspberry-pi-node-mqtt--esp32 An IoT demo project using ESP32 to send sensor data (humidity, temperature) to a Raspberry Pi via MQTT. Node-RED is used for data visualization and control. Secure ...

The ESP32 based sensor nodes publish their readings to an MQTT broker running on the Raspberry Pi. The Pi subscribes to these sensor node topics to pick up the relevant sensor data.
