## About
|
|
|
|
The Environment Measurement Plugin will allow nodes to send a specific message with information from connected environmental sensors. Currently supported sensors are DHT11 and Dallas 1-wire DS18B20. This plugin does only work on ESP32 devices.
|
|
|
|
## Configuration
|
|
|
|
These are the settings that can be configured.
|
|
|
|
environmental_measurement_plugin_enabled
|
|
Is the plugin enabled?
|
|
|
|
0 = Disabled (Default)
|
|
1 = Enabled
|
|
|
|
environmental_measurement_plugin_screen_enabled
|
|
Show received sensor readings on device screen.
|
|
|
|
0 = Disabled (Default)
|
|
1 = Enabled
|
|
|
|
environmental_measurement_plugin_read_error_count_threshold
|
|
Error count threshold for failed sensor readings.
|
|
|
|
Default = 0
|
|
|
|
preferences.environmental_measurement_plugin_update_interval
|
|
How often (in seconds) should sensor readings be broadcasted?
|
|
|
|
Default = 0
|
|
|
|
environmental_measurement_plugin_recovery_interval
|
|
For how long should we wait (in seconds) before trying to read sensors again upon exceeded error threshold?
|
|
|
|
Default = 0
|
|
|
|
environmental_measurement_plugin_display_fahrenheit
|
|
Should temperature readings be converted to fahrenheit?
|
|
|
|
0 = Disabled (Default)
|
|
1 = Enabled
|
|
|
|
environmental_measurement_plugin_sensor_type
|
|
What sensor is connected?
|
|
|
|
0 = DHT11 (Default)
|
|
1 = Dallas 1-wire DS18B20
|
|
|
|
environmental_measurement_plugin_sensor_pin
|
|
Which pin is the sensor connected to?
|
|
|
|
Default = 0
|
|
|
|
|
|
## Usage Notes
|
|
|
|
For basic usage, start with:
|
|
|
|
environmental_measurement_plugin_enabled = 1
|
|
|
|
environmental_measurement_plugin_screen_enabled = 1
|
|
|
|
Depending on which pin your sensor is connected to, set it accordingly:
|
|
|
|
environmental_measurement_plugin_sensor_pin = 13
|
|
|
|
|
|
:::note
|
|
The device must be restarted after the settings have been changed for the plugin 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

|
|
## Known Problems
|
|
|
|
* No default configuration values are currently set, so this must be done when enabling the plugin.
