Gravity: BLE Sensor Beacon Pack (5 PCS)

Note: Gravity BLE sensor beacons must be configured with the 3.3V USB - TTL tool. This amazing Gravity wireless BLE Sensor Beacon, built with an 11 - bit ADC, can collect data from digital and analog sensors and broadcast it via Bluetooth. You can easily access the sensor data on a Bluetooth - enabled device like a smartphone or ESP32 within the broadcasting range. Integrated with the advanced low - power BLE 5.3 technology, it supports both LE and private - protocol broadcasting. Its data format is compatible with iBeacon, Eddystone, and other mainstream protocols. You can customize the data format, broadcast content, and time intervals on a user - friendly graphical interface. Once configured, it acts as a Bluetooth beacon when powered on, automatically collecting and broadcasting data as per your settings. These sensor beacons are great for IoT sensor nodes in various scenarios such as smart farms, offices, factories, and warehouses. Features: Bluetooth Low Energy 5.3 Compliant. Applications: IoT, smart farms, smart offices, smart factories, smart warehouses. Specification: Operating Voltage: 3.3 - 5.5V DC; Beacon Operating Current: <5µA; Input Signal: digital/analog signal; Operating Frequency Range: 2.4GHz ISM; Modulation: GFSK; Transmitting Power: +5.0dBm; PCB Size: 27mm*33.5mm/1.06*1.32'; Mounting Hole Size: inner diameter of 3.1mm/outer diameter of 6mm.

Using this Gravity BLE Sensor Beacon Pack is easy. First, use the 3.3V USB - TTL tool to configure the beacons as you need on the graphical interface. You can set things like the data format, what to broadcast, and how often. Once configured, just power them on, and they'll start working as Bluetooth beacons. They'll collect data from digital or analog sensors and broadcast it. You can access this data on your Bluetooth - enabled devices like smartphones or ESP32s when you're within the broadcasting range. Remember, these beacons need an operating voltage between 3.3V and 5.5V DC. Try to keep them in a place where the operating frequency of 2.4GHz ISM won't be interfered with. For maintenance, make sure to keep the PCB clean and dry. If you want to learn more, check out the product wiki and schematics.
