Delivering Ultra-Low Power IoT for the Real World

Medical Devices

The BL654 excels in mission-critical environments like hospitals, providing secure wireless connectivity for medical peripherals.

BL654 Applications - Medical

Industrial Automation

Sensor data can provide deep insights needed to maintain energy efficiency and productivity within factories and manufacturing plants. Monitor and control temperatures, energy usage, output, downtime vs. uptime, and other critical metrics.

BL654 Applications - Industrial

Remote Security Monitoring

The BL654 excels with home security devices like door, window, and air-quality sensors. A BL654-powered home security system can broadcast its status regularly to a monitoring base. As many as eight peripherals can be connected to the system via Bluetooth Low Energy, creating a hub of smart BLE home sensors.

BL654 Applications - Security

Connected Appliances

Securely and remotely take control over household appliances like refrigerators, dish washers, coffer makers and more. Monitor and automatically get notified about food stock levels, energy usage and dishwasher status to create a more productive lifestyle.
