USB Thermometer - 55 C to +
125 C
USB thermometer is a small module with
good electrical properties. Thermometer is connected with the PC via
USB
cable and is also powered via this cable. Temperature values
are displayed
on the monitor of a PC. It has 2 inputs, so you can measure 2
temperature at the same time.
It has an operating temperature range of -55 C to +125 C and is accurate to 0.5 C over the range of -10 C to +85 C.
It has an operating temperature range of -55 C to +125 C and is accurate to 0.5 C over the range of -10 C to +85 C.

USB Thermometer
Range : -55 to
+ 125 C
Power suply : from PC via USB connector Software : USB Measure + API ( build your own application ) Paralel
connecting : up to 127 devices connected is
possible |
||||||||
This thermometer is
galvanically connected with a PC. It is possible to simultaneously
connect up to 127 USB thermometers. Temperature sensor DS18S20 is
connected to the module with cable and the cable length may be several
meters. This sensor does not need any adjustment.
Software + API
|
Software.
Software in the PC communicates with the USB device and display data on the monitor. Once installed it is already capable to work immediately.There is no need for settings. Software can communicate with multiple USB device at the same time. It also allows logs measured data into log file. COM component. For developers is supplied COM component, that enables to create own applications. COM component works with all popular languages like visual basic, C/C++, C#, javascript etc. More info are in help and in the software page. |

USB Thermometer block diagram
1. Temperature sensor.
As a temperature sensor is used DS18S20. This is a temperature sensor with digital output. It has an operating temperature range of -55 C to +125 C. The DS18S20 communicates over a 1-Wire bus with microcontroller. 2. microcontroller as thermometer.
Microcontroller PIC16F886 communicates with DS18S20 and read from it the measured value. Measurement is approximately 3 times/sec . Microcontroller sends the measured data to PC. 3. USB interface and PC communication.
Connection with PC is implemented by using USB converter with FT 232RL. FT 232RL is a reliable converter from USART to the USB protocol. It uses its own APIs and offers a lot of capacity for communication PC with a USB device.
