Wearable and wireless connected monitoring devices can safeguard the user in many potentially hazardous environments.
Bluetooth Connected Respirable Dust Sensor
This is a standalone board designed for a specific application and is not for general sale. However, Design Interface Ltd is well placed to implement any wireless based system that you may require.
The Bluetooth module on this sensor board integrates two ARM Cortex MCUs, one to manage the radio and another to run the application software. This board communicates with a particle sensor (not shown) and displays readings on an OLED display (not shown). Operating parameters can be loaded over the Bluetooth interface so that alarms (audio and visual) will occur if dust thresholds are exceeded. Similarly log information can be uploaded to and displayed in a browser app in real time or at the end of a shift. This design is used in a wearable respirable dust sensor and will raise the alarm if the dust level across a number particle size ranges exceeds safe limits.
