Graphing Yocto-Watt measures with Yocto-Visualization

By seb, in Measures, august 27,2022.

At Yoctopuce, we like to travel by electric bike and we have decided to measure the charge of an electric bike battery with a Yocto-Watt and the Yocto-Visualization application. This doesn't require any programming, but a rather good knowledge of Yocto-Visualization to obtain a readable and pretty graph. We thought that monitoring the electrical consumption of a device could interest other people. Here is what we did.

Controlled watering system

By Tiago, in Measures, august 20,2022.

At Yoctopuce, we like raspberries. So we thought that we would have our own local production, with an automatic watering system controlled by our modules. To do so, we retrieved a raspberry bush from the garden and we planted it in a pot with sensors to monitor its health. The aim is to adjust the water dispensing based on the humidity of the soil. Unfortunately, it's too late in the season to have raspberries this Summer, but we are still going to tell you about the modules used to maintain the raspberry bush alive.

How to build a USB current clamp

By mvuilleu, in Measures, june 10,2022.

A few years ago, we demonstrated how to use a Yocto-milliVolt-Rx to measure DC current, by measuring the very low voltage at the terminals of a shunt resistor. More recently, we thought that it could be useful to extend this scenario to the measure of strong alternative currents using simple ring-shaped current transformers, like current clamps.

Using a proximity sensor behind a window

By mvuilleu, in Measures, march 25,2022.

Infrared proximity sensors, such as the Yocto-Proximity, are an effective alternative to pressure switches in order to detect when an object has been placed at a given location. But for reliable and robust use, you must respect a few implementation rules, especially if you put a protective glass in front of the sensor.

Using inertial sensors in a vehicle

By mvuilleu, in Measures and Misc, february 11,2022.

MEMS inertial sensors used in products such as the Yocto-Inclinometer or the Yocto-3D-V2 can determine their orientation with regards to terrestrial gravity, like an electronic spirit level. It is tempting to use them to measure the orientation of moving objects, such as vehicles, but it's not as easy as we might hope. Here are some explanations on the difficulties one might expect, as a reminder of your kinematic physics courses...
