Request for Assistance with Physics Laboratory Kits for High School Students

Post by NIEduard »

Hi,

My name is Eduard Nastase, and I am both a researcher and an educator at a FabLab. I am reaching out to seek your assistance in constructing physics laboratory kits for high school students. These kits will be utilized to deliver engaging lessons and experiments.
The projects are based on Arduino boards, and I am in need of the following five sensors, which must be compatible with Arduino and meet the minimum specifications listed below:

Minimum requirements:

1. Motion detection sensor:
Distance = (0,100 – 3.000 ± 0,001) m
Velocity = ± 10 m/s
Acceleration = ± 30 m/s/s
Minimum Sample Rate: 100 Hz

2. Gas pressure sensor:
Pressure Range: 0 to 400 kPa;
Precision: ± 1 kPa;
Resolution: 0,1 kPa;

3. Temperature sensor:
Temperature Range: -20 to +120°C;
Resolution: 0,1°C;
Minimum Sample Rate: 100 Hz;

4. Voltage-Current sensor:
Range: ±1 A & ±1 V;
Accuracy: ± 1%;
Minimum Sample Rate: 1 kHz;

5. Light sensor:
Illuminance Range: 0 to 100.000 lux;
Resolution: 1 lux until 6.000 lux;
Spectral Response: 350 to 1.000 nm;

So far, the size of the sensor doesn't matter.
It is essential that the sensor is compatible with Arduino. Please provide specific details about the connectivity to ensure effective integration into the system.

Your expertise and support in sourcing these sensors would be invaluable to us and greatly appreciated. We believe that with your help, we can provide a more enriching educational experience for the students.

Thank you for considering my request. I look forward to your positive response.

Best regards,
Eduard Nastase

A BME280 would get you temperature, humidity and pressure.

The MMA8451 would provide motion.

The INA219 for current / voltage.

The VEML7700 for lux.

All of these are i2c stemma qt so you would need stemma qt cables to connect devices and one with male a header side connect to an Arduino.

That one is not a stemma connected board. Perhaps you means to suggest a different one?

Minimum requirements:

1. Motion detection sensor:
Distance = (0,100 – 3.000 ± 0,001) m
Velocity = ± 10 m/s
Acceleration = ± 30 m/s/s
Minimum Sample Rate: 100 Hz
I don't know of any single sensor that could meet all of those requirements for a reasonable price.

An accelerometer such as the MMA8451 suggested above will easily meet the acceleration requirements. And *in theory* you can integrate the acceleration over time to compute velocity and further integrate the velocity over time to compute the total distance traveled. However, the errors from quantization, noise and floating-point computations will rapidly accumulate with the double-integration. And in practice, the velocity and position calculations become mostly unusable after only a few seconds.

An inertial navigation system capable of meeting all of the stated requirements would cost several orders of magnitude more than an MMA8451.

@Timeline, correct, there are some stemma connected ones depending on what they need at https://www.adafruit.com/category/682 specifically https://www.adafruit.com/product/4097
