A lightweight, interactive sensor reader for the DHT11 temperature and humidity module, designed specifically for the Flipper Zero running Momentum Firmware.
- Interactive menu UI (Acquire Data, Configuration, About, Exit)
- Configuration for:
- ✅ GPIO pin (PB3, PB2, PC3)
- ✅ Units (Celsius or Fahrenheit)
- ✅ Read interval (1s, 1 min, 5 min)
- Persistent settings saved to
ext/dht11_sensor.cfg - Uses DWT-based microsecond timing for stable DHT11 reads
- Graceful app exit with
[Back]
To run this proof-of-concept, you will need:
- ✅ A Flipper Zero device running Momentum Firmware
- ✅ A DHT11 sensor module, commonly available from:
- Amazon
- Digitec
- AliExpress
- or other electronics distributors
Ensure proper wiring between the sensor and Flipper GPIO headers.
Under Momentum Firmware structure applications_user create this:
applications_user/ └── dht11_sensor/ ├── dht11_sensor.c ├── dht11_sensor_icon.png └── application.fam
Run ufbt to compile the .fap app
ufbt dht11_sensor
Copy the compiled app .fap under /dist folder to your apps/ directory in your flipper0 runing Momentum. i.e you can use qfliper interface
DHT11 Flipper GPIO ===== ============ VCC → 3V GND → Pin 3 (GND) DATA → Pin 5 (PB3) — default or Pin 6 (PB2), Pin 7 (PC3)
