Yoctopuce Yocto - Serial Sensor Adapter
This serial sensor adapter is compatible with Valarm Tools Cloud!
The device is a USB to serial adapter, similar to the RS-232, except it uses logical ( TTL / CMOS ) signal levels at 0/3.3V or 0/5V. The module does not require a driver and does not install a virtual COM port.
It is able to autonomously interpret serial data coming from any external serial board and expose measures as if they came from a Yoctopuce sensor, with all of the features like a unique identifier, polling, and callbacks. Be aware that this device will not work with applications designed to use a COM port: it is designed to be used with Yoctopuce API only and is meant to be used with Wifi sensor hubs and Ethernet sensor hubs.
If needed, the device can also provide a 3.3V or 5V voltage source to power the external serial board. The 3.3V source can provide up to 200mA.
The device can work with standard logical levels (signal high when the line is idle), or with inverted levels. RTS/CTS can only be used with standard logical levels. The device can also analyze a serial bidirectional communication between two tiers without interference.
If you need to interface a serial port working with RS232 levels, use a Yocto-RS232. If you need to monitor particulate matter and an optical particle counter sensor like the Alphasense OPC-N2, you'll use this SPI sensor adapter.
