+## About
 
-:::caution
-This is a work in progress and is not yet available.
-:::
+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.
