Sensa Gram

Stream Android sensor data over UDP with minimal latency.
New in version 1.4.1
Resolved an issue where the runtime location permission dialog was not displayed when requesting access to the device's location
Transform your Android device into a dynamic sensor hub with Sensagram, offering seamless real-time data streaming. Sensagram allows you to seamlessly stream live sensor data over UDP, ensuring low latency

Effortlessly broadcast a wide range of Android sensors, including motion, position, environmental, and GPS (location) data, directly to a specified IP address or server, making it the perfect tool for developers, researchers, and tech enthusiasts.

Key Features:

Real-time Streaming: Transmit sensor data in real time for accurate and immediate feedback.
Comprehensive Sensor Support: Stream data from motion (gyroscope, accelerometer), position (magnetic field, rotation vector), environmental (light, temperature), and GPS (location) sensors.
Low Latency with UDP: Experience the speed and efficiency of UDP, providing minimal delay in data transmission, ideal for time-sensitive applications.
Customizable Endpoints: Easily configure and send data to your desired IP address or network endpoint.

In the app, select the desired sensors from the list and tap the "Stream" button. This will begin transmitting sensor data to the specified address. To receive the data, you'll need to set up a UDP server. The app sends the data in JSON format.

    • access location in the background
      This app can access location at any time, even while the app is not in use.
    • access approximate location only in the foreground
      This app can get your approximate location from location services while the app is in use. Location services for your device must be turned on for the app to get location.
    • access precise location only in the foreground
      This app can get your precise location from location services while the app is in use. Location services for your device must be turned on for the app to get location. This may increase battery usage.
    • view network connections
      Allows the app to view information about network connections such as which networks exist and are connected.
    • view Wi-Fi connections
      Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices.
    • recognize physical activity
      This app can recognize your physical activity.

      Allows the app to make use of foreground services with the type "specialUse"
    • access sensor data at a high sampling rate
      Allows the app to sample sensor data at a rate greater than 200 Hz
    • have full network access
      Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.
    • show notifications
      Allows the app to show notifications
    • run at startup
      Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.
