![]() Old problem talked about in the previous post. But at the same time this might but a possible way to fix up problem one - find a position where detecting the vibration is possible and at the same time voltage is not too high. ![]() That means we are not able to put the sensor anywhere we want. Which suggests that the position of how we put the sensor is really essential for the sensitivity. The off-axis sensitivity of the sensor is really low. The vibration of the surface of the drum may not be strong enough to produce a voltage higher than 5V, but if it does, we need to deal with it. ![]() The voltage could be more than 50V depends on the vibration which is way higher than 5V. Depends on the resonance or not, the voltage sensitivity could be 1.1V/g or 6V/g (proportional to the acceleration). The voltage the sensor produces could be higher than the voltage threshold(5V) of the micro controller. However, there are two problems with this vibration sensor. It converts vibration to voltage and thus is able to do either continuous vibration or impacts. ![]() MiniSense 100 Vibration Sensor is an excellent accelerometer with an affordable price. Exploration of the microphone sensor will be introduced in next week’s blog post. My blog this week will be centred around the use and problem with MiniSense 100 Vibration Sensor. This week’s work is focused on the software end, Will is in charge of network part (WiFi and the server) and I will be working on data processing (getting input data from the sensor and apply data processing and math methods on the raw data). ![]()
