I am developing simple circuit where I am trying to detect pressure when arms coming together when hand bended. the device will be placed near the L bow of hand and when user bend the arm, the device measure the pressure and beep if pressure is higher than set limit.
I know micro controller...
I am trying to make a pressure sensor using a CS040 sensor. The manufacturer sent me a complicated constant current circuit to power the sensor, but I wonder if there is a simpler way to power it.
The sensor is piezoresistive. It outputs a voltage that varies with the pressure applied...
I have a ultra low differential pressure sensor in a flow meter configuration(Venturi meter). https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Data+Sheet%7FSM9000%7FA1%7Fpdf%7FEnglish%7FENG_DS_SM9000_A1.pdf%7FCAT-BLPS0062
Through help from the members...
I need your help to making work the pressure sensor MPS20N0040D (module with hx7110) , I uploaded the sketch , but I can't get a right graphic , it's seems to be not fonctional !!!
It's the same graphe with & without the module connected
To the arduino !!!
