+# Temperature sensors
+
+It is now possible to measure temperatures with the help of the I²C LM75 and 1-Wire DS18B20 chips. The temperature values can be displayed on the OSD and they are also logged. A total maximum of 8 temperature sensors can be connected.
+
+## LM75
+
+Up to 8 can be connected to the flight controller.
+
+* Package: SOP-8, breakout boards can be found easily
+* Interface: I²C
+* Supply: 2.7 to 5.5V
+* Temperature range: -55 to +125°C
+
+## DS18B20
+
+* Package: TO-92, SO-8, µSOP-8
+* Interface: 1-Wire
+* Supply: 3.0 to 5.5V (parasitic power not supported)
+* Temperature range: -55 to +125°C
+
+None of the flight controllers on the market at the time this documentation is written supports 1-Wire directly. To use these sensors a I²C to 1-Wire interface chip needs to be used, the DS2482. Connect the DS2482 SCL and SDA lines to your FC, add a 4.7kohm pull-up resistor between VCC and the DQ pin then connect all the sensors DQ pin to the DS2482 DQ pin.
+
+## Configuring temperature sensors
+
+The `temp_sensor` CLI command can be used to display and change the temperature sensors configuration. When a new temperature sensor is connected it is automatically detected and will appear in the output of the `temp_sensor` command.
+
+* `temp_sensor` without any argument displays all the sensors configuration
+* `temp_sensor reset` deletes all the sensors
+* `temp_sensor index type address alarm_min alarm_max label` to configure a new sensor or modify the configuration of an existing one.
+
+### Parameters description
+
+* `index` is the index of the configuration slot you want to change
+* `type` can be `1` for LM75 or `2` for DS18B20
+* `address` is the address of the device on the bus. 0 to 7 for a LM75 or the full 64bit ROM in hex format for a 18B20
+* `alarm_min` the temperature under which the corresponding OSD element will start blinking (decidegrees centigrade)
+* `alarm_max` the temperature above which the corresponding OSD element will start blinking (decidegrees centigrade)
+* `label` a 4 characters maximum label that is displayed on the OSD next to the temperature value
+
+### Example output
+
+Example output of the `temp_sensor` command on a system with two LM75 and four DS18B20 sensors connected
