bosch module

This bosch module implements a bosch BME280 environmental sensor, used for sensing temperature, humidity, and barometric pressure using the rdk:component:sensor API.

Note

Before configuring your sensor, you must create a machine.

Configure your bme280 sensor

Navigate to the CONFIGURE tab of your machine in the Viam app. Add sensor / viam:bosch:bme280 to your machine.

On the new component panel, copy and paste the following attribute template into your sensors’s attributes field:

{
  "i2c_bus": "<your-i2c-bus-index-on-board>",
  "i2c_address": "<your-i2c-address>"
}

Note

For more information, see Configure a Machine.

Attributes

The following attributes are available for viam:bosch:bme280 sensors:

Attribute	Type	Required?	Description
i2c_bus	string	Required	The index of the I2C bus on the board that the sensor is wired to.
i2c_address	string	Optional	Default: 0x77. The I2C device address of the sensor.

Example configuratiosn

viam:bosch:bme280

  {
     "name": "<your-bosch-bme280-sensor-name>",
      "model": "viam:bosch:bme280",
      "type": "sensor",
      "namespace": "rdk",
      "attributes": {
        "i2c_bus": "<your-i2c-bus-index-on-board>",
        "i2c_address": "<your-i2c-address>"
      },
      "depends_on": []
  }

Next Steps

• To test your sensor, expand the TEST section of its configuration pane or go to the CONTROL tab.
• To write code against your sensor, use one of the available SDKs.
