Adafruit just posted an awesome tutorial on reading analog sensors with the Raspberry Pi. It’s a great walkthrough that can be applied to your next Raspi project as well as any project where you ...

Resolution [bit]: the number of bits to represent a digital signal. Sampling rate [Hz]: how fast they work. ADC Symbol. An 10-bit ADC with 1 kHz sampling rate has 256 (2⁸) levels in its digital signal ...

I just wanted to see how well the cadmium sulfide cell would detect full light and full dark conditions and maximize the range resistively. I selected channel 2 and ran program 1-3 and once again, I ...

This makes it better for simple projects. It also has a 'true' UV sensor instead of a calibrated light-sensor. To use, power the sensor and op-amp by connecting V+ to 2.7-5.5VDC and GND to power ...

Two configurable analog ports allowyou to connect many sensor types usingtwo three-input connectors, each ofwhich has a ground pin (Figure 4). Oneground pin provides 3.3V power, andthe other outputs ...

3. An IoT SoC can support analog interfaces to the sensor. Advantages Of An Integrated Analog Interface. Any IoT system needs to be able to support analog and digital sensors to be truly flexible.

Analog pH sensors output a small analog voltage signal, generally in the millivolt range, that corresponds linearly to the pH value. This voltage signal is continuous and varies smoothly as the pH ...

In this work, an analog read-out circuit, based on a fully differential topology, employed for differential capacitive sensors, is presented. The proposed solution is based on differential ...
