The Yocto-PWM-Rx is a 2 channels PWM input. Each channel can report frequency, duty cycle, and pulse length. It works from 0.05Hz to 250Khz and accepts any -30..+30V signal as long as it crosses the 0.7V threshold.
Each channel also features a pulse counter linked to a time counter. This allows to integrate over time the output of sensors such as flow-meters. The pulse counter works from 0 to 250kHz.
The two PWM inputs are galvanically insulated from the USB bus. This will allow you to connect the Yocto-PWM-Rx to main-powered equipments without risking to fry your computer.
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
USB cables and enclosure to be ordered separately.
I'd like to change the frequency Hz value to CPS (Counts per Second). I'd also like change the reported edge count to a singular event per pulse (1/2 value). How do I do this ?
Is there a way of simple doing this without digging to far into the APIs?
@cjw: The unit is hard-coded into the device and cannot be modified. The events count is done in hardware, and this hardware cannot tell the difference between up and down transitions, that's why the device reports edges count, not pulses count.
