FipperZero-DHT-Monitor

Flipper Zero plugin for monitoring air temperature and humidity using DHT11 and DHT22 (AM2302/AM2301) sensors

No longer supported. Use Unitemp

Capabilities

• Support for DHT11/DHT22(AM2302)/AM2301 sensors
• Ability to work with sensors without strapping
• Free choice of I/O ports
• Automatic power on 5V output 1
• Saving settings to an SD card

Installation

Copy the contents of the repository to the applications/plugins/dht_monitor folder and build the project. Flash FZ along with resources.

Or use the plugin included with Unleashed Firmware

Connecting

Sensor pin	Flipper Zero pin
VCC (none, +, VCC, red wire)	1 (5V) or 9 (3V3)
GND (-, GND, black wire)	8, 18 (GND)
DATA (OUT, S, yellow wire)	2-7, 10, 12-17 (to choose from)

The selected pin of the DATA line must be specified when adding a sensor in the application.

Usage

1. Connect the sensor to FZ.
2. Launch the application and press the center button. Select "Add new sensor".
3. Specify sensor parameters - name, type, pin.
4. Click "Save". The next time you launch the application, the saved sensors will be loaded automatically. You can delete or change sensor parameters in the main menu.

fipperzero-dht-monitor's Issues

Build fail: Undeclared InputKeyMAX

The following error occurs on build with Official firmware 0.7

CC      applications/plugins/FipperZero-DHT-Monitor-1.1/quenon_dht_mon.c
applications/plugins/FipperZero-DHT-Monitor-1.1/quenon_dht_mon.c: In function 'quenon_dht_mon_app':

Error: Load failed. Found unsatisfied imports

When I run a fap file on FZ I get an error: Load Failed. Found unsatisfied imports. Is it due to API mismatches?

'kernel panic' on any key press

After init phase, where 'No sensors found' message displayed, when I press any button, the firmware crashes and flipper reboots with 'assert failed' message on recovery.

DHT11 - Timeout

Hey, thank you for what you are doing. Just facing a hopefully small issue.

I have the DHT11 and I have plugged directly like you have shown in the pictures. Created a new sensor in the app, and set the pin read to 10.

However, It does not seem to be able to get a reading. It is stuck at
"Timeout"

What am I doing wrong?
