## About
|
|
|
|
The Telemetry Module will allow nodes to send a specific message with information from connected sensors. Currently supported sensors are `BME280`, `BME680`, `DHT11`, `DHT12`, `DHT21`, `DHT22`, Dallas 1-wire `DS18B20`, and `MCP9808`.
|
|
|
|
The preferred setup is using I2C, so the `telemetry_module_sensor_pin` may not be needed.
|
|
|
|
## Usage Notes
|
|
|
|
For basic usage, start with:
|
|
|
|
```shell
|
|
telemetry_module_enabled = 1
|
|
|
|
telemetry_module_screen_enabled = 1
|
|
```
|
|
|
|
Depending on which pin your sensor is connected to, set it accordingly:
|
|
|
|
```shell
|
|
telemetry_module_sensor_pin = 13
|
|
```
|
|
|
|
:::note
|
|
The device must be restarted after the settings have been changed for the module to take effect.

## Hardware
|
|
|
|
The sensors can be wired differently, here's one example for sensor DS18B20 https://randomnerdtutorials.com/esp32-ds18b20-temperature-arduino-ide

## Example of T-LoraV1 with DHT22 temperature sensor
|
|
|
|
Setup of a T-LoraV1 with DHT22 temperature sensor.
|
|
|
|
[<img src="T-LoraV1 with DHT22" src="/img/hardware/lora_v1_with_DHT22.jpg" style={{zoom:'25%'}} />](/img/hardware/lora_v1_with_DHT22.jpg)
|
|
|
|
Requirements:
|
|
|
|
- T-LoraV1 (but any esp32 should work, just be sure to double check which GPIO to use)
|
|
- DHT22 sensor
|
|
- 10 Kohm resistor (optional, but recommended)
|
|
- breadboard (optional)
|
|
- two red wires (could be a different color, but 5V is typically red)
|
|
- two yellow wires for GPIO (could be a different color)
|
|
- one black wire (could be a different color, but GROUND is typically black)
|
|
|
|
Steps:
|
|
|
|
- disconnect power/battery
|
|
- connect black wire from GROUND to "-" on the DHT22
|
|
- connect yellow wire from middle PIN to a row on bread board
|
|
- connect red wire from 5V to a row on breadboard
|
|
- connect resistor between red and yellow rows
|
|
- connect red wire from row with red to "+" on DHT22
|
|
- connect yellow wire from yellow row to GPIO on device (ex: GPIO21)
|
|
- double check the cabling (if you get it wrong, you can damage the device and/or the DHT22 sensor)
|
|
- plug in device
|
|
- configure the device:
|
|
|
|
```shell
|
|
meshtastic --set telemetry_module_measurement_enabled true --set telemetry_module_screen_enabled true --set telemetry_module_update_interval 15 --set telemetry_module_display_farenheit true --set telemetry_module_sensor_type DHT22 --set telemetry_module_sensor_pin 21
|
|
```
|
|
|
|
:::tip
|
|
You can change the values above to suit your needs. The commands can be run one at a time or in a group as show above.
|
|
:::
|
|
|
|
- reboot/reset the device (press the RST button or unplug/plug in the device)
|
|
- when the device boots it should say "Telemetry" and it may show the sensor data
|
|
- if "no data", then triple check the wiring
|
|
- if still "no data", run:
|
|
|
|
```shell
|
|
meshtastic --info
|
|
```
|
|
|
|
and verify the the `telemetry_module_sensor_type and` `telemetry_module_sensor_pin`

## Configuration
|
|
|
|
Configuration details are available on the [Device Settings](/docs/settings) pages. Configuring the Telemetry Module requires configuring the following modules:
|
|
- [Telemetry Module](/docs/settings/modules/telemetry-module)
|
|
|
|
## Known Problems
|
|
|
|
- No default configuration values are currently set, so this must be done when enabling the module.
