USB Sensors and Actuators
Yoctopuce designs, manufactures and sells USB devices to let your computer sit in the real world. Our USB modules are tiny, easy to install and easy to drive programmatically. Among them you will find:
USB to SDI-12 interface, with data analyzer.
This isolated device can decode PWM signals. You can use it as a pulse counter as well.
Application examples, hints and tutorials
A while back, the Commission de l'inspection paritaire des entreprises (Joint Labor Inspection Commission) for the Canton of Geneva issued us a formal notice requiring us to implement a system for tracking work hours for all staff. Until now, Yoctopuce had operated on a trust-based system, and that had never caused the slightest problem. But hey, the law is the law, so we had no choice but to comply :( So, since we had to track work hours anyway, we figured we might as well do it the Yoctopuce way :)
Uploading firmware with XMODEM/YMODEM
XMODEM and YMODEM are protocols that enable reliable file transfers over a serial connection (UART). They were designed 50 years ago to improve the reliability of data transfers over analog telephone lines, and one might have expected them to have disappeared completely by now. However, there are still a few specific cases where they are widely used, which is why we have just added native support for these protocols in our serial communication modules.
