SNR-I200 | Wireless Impact Detection Sensor

Impact Detection Sensor

The Wireless Accelerometer - Impact Detect Sensor is a digital, low power, low profile, capacitive sensor that is able to measure acceleration on three axes to detect impact over a set g-force threshold. The  Wireless Accelerometer - Impact Detect Sensor activates when g-forces are exceeded by a user defined threshold – up to 8 g-force. The user can key in the desired threshold for the g-force trigger. This sensor has two operation modes that can be also selected by the user: High Performance and Low Power. High Performance has an output data rate of 800 Hz with the High Pass Filter cutoff at 16 Hz while the Low Power has an output data rate of 12.5 Hz with the High Pass Filter cutoff at 0.25 Hz. The data is displayed as “Force Detected” or “No Force Detected”.
