Bluetooth Low Energy (BLE) Temperature Sensor Beacons are compact, wireless devices that utilize BLE technology to monitor and record temperature data. These beacons can be integrated with various sensors to provide contextual information and transmit the collected data to a server for further analysis. The BT01 temperature beacon, for example, is a high-quality, smart BLE Temperature Sensor Beacon that guarantees high performance with a range of settings for every wireless temperature sensing and logging need.
Understanding BLE Technology
BLE is a form of wireless communication designed for short-range communication, prioritizing battery life over high data transfer speeds. It operates in the 2.4 GHz frequency band and uses a technique called Frequency Hopping Spread Spectrum (FHSS) to minimize interference and improve reliability.
BLE devices communicate by advertising their presence and transmitting data packets. These packets can contain various types of information, including sensor data, device identification, and other contextual information. BLE devices can also connect to each other and exchange data in a more structured manner, known as a BLE connection.
Technical Specifications of BLE Temperature Sensor Beacons
The BT01 BLE Temperature Sensor Beacon, for example, has the following technical specifications:
| Specification | Value |
|---|---|
| Wireless Technology | Bluetooth Low Energy (BLE) 5.0 |
| Transmission Range | Approximately 500 meters |
| Enclosure | IP67 waterproof and dustproof |
| Temperature Measurement Range | -40°C to +85°C |
| Temperature Measurement Accuracy | ±0.3°C |
| Sampling Rate | Configurable from 1 second to 1 hour |
| Battery Life | Up to 5 years (depending on usage) |
| Dimensions | 60 x 60 x 20 mm |
| Weight | 50 grams |
The BT01 beacon converts the environmental temperature into a corresponding digital signal, which can then be uploaded to a server through a wireless network connection.
Understanding the Data Transmitted by BLE Temperature Sensor Beacons
To better understand the data transmitted by a BLE Temperature Sensor Beacon, let’s examine a real-world example using an ELA temperature and ID sensor:
- The Service Data contains a 2-byte data type indicator, in this case,
6E2A, which indicates temperature data. - The temperature data is contained in the next 2 bytes in Intel byte order, with the most significant byte last (
AB0A). - Reversing the byte order results in
0AAB, which in decimal is2731. - As per the datasheet, we scale the result by multiplying with 0.01 to realize a temperature of 27.31 degrees Celsius.
This process of interpreting the data transmitted by a BLE Temperature Sensor Beacon is crucial for understanding the environmental conditions being monitored.
Integrating BLE Beacons with Sensors
BLE beacons can be paired with various sensors to capture additional data and provide contextual information. For instance, a beacon can incorporate sensors to monitor ambient temperature, preventing equipment damage due to extreme temperature variations.
When beacons are integrated with sensors, they can emit relevant sensor-collected information, such as temperature fluctuations, alongside their positioning signal. This allows for more comprehensive monitoring and analysis of the environment.
Some examples of sensors that can be integrated with BLE beacons include:
- Temperature sensors
- Humidity sensors
- Light sensors
- Motion sensors
- Proximity sensors
- Air quality sensors
By combining the capabilities of BLE beacons and various sensors, users can gain a deeper understanding of their environment and make more informed decisions based on the collected data.
Applications of BLE Temperature Sensor Beacons
BLE Temperature Sensor Beacons have a wide range of applications, including:
- Cold Chain Monitoring: Tracking the temperature of perishable goods during transportation and storage to ensure product quality and safety.
- Facility Management: Monitoring the temperature in buildings, warehouses, and other facilities to optimize energy usage and prevent equipment damage.
- Environmental Monitoring: Tracking temperature and other environmental conditions in outdoor settings, such as agricultural fields, forests, and wildlife habitats.
- Industrial Automation: Monitoring the temperature of machinery and equipment to predict maintenance needs and prevent breakdowns.
- Healthcare: Monitoring the temperature of patients, medical equipment, and storage facilities to ensure proper care and compliance with regulations.
By leveraging the capabilities of BLE Temperature Sensor Beacons, organizations can improve efficiency, reduce costs, and enhance their overall operations.
