Hello,

I need to purchase temperature, humidity, air velocity and vibration (or accelerometer) sensors. I will place the sensors in the engine compartment of my car near the headlamp (in a place where it is not very hot).
Below you can find some specifications:
Operational temperature range: -40 C to 85 degrees (or more)
Humidity: 0 to 95%.
Air velocity: 0 to 20 m/s (preferably omnidirectional).
Frequency range: 1Hz to 500Hz.
Max operating range: 10g.
Sensitivity: 100mV/g or more.
My concern is that the sensors must be small and resist to the harsh environment (electromagnetic radiations, vibration, saline fog, condensation, extreme temperatures….) that we find in vehicle.
I haven’t found any companies that make those kinds of sensors dedicated to the measurements in vehicle engine compartment.
Could you help me? Thank you.
