# Sensors

A sensor can be associated with a [floor](https://docs.butlr.io/asset-management/graphql-api-overview/floors), [room](https://docs.butlr.io/asset-management/graphql-api-overview/rooms), or [zone](https://docs.butlr.io/asset-management/graphql-api-overview/zones). This flexibility allows for effective monitoring across different areas, from general traffic at floor entrances to pinpointing specific occupancy locations within a zone.

This page provides guidance on how to [**retrieve**](#get-all-sensors), [**create**](#create-sensor-s), and [**update sensor information** ](#update-sensor-s)within an organization.

### Get all sensors

```graphql
query allSensors {
  sensors {
      data {
          client_id
          floor_id
          room_id
          hive_id
          hive_serial
          sensor_id
          name
          mac_address
          mode
          model
          sensitivity
          center
          height
          orientation
          field_of_view
      }
  }
}
```
