Perfekt für schnelles und genaues Ergebnis

For USB Thermometer

Ich habe mehrere dieser Geräte gekauft und Abweichungen bei der Temperatur sind minimal im 0,0X°C Bereich. Gleichzeitg wird die Anzeige mit digitemp.exe mit °C und als °F geliefert. Bin sehr positiv überascht von der Qualität und dem schnellen Versand. Einfach empfehlenswert!

Really nice product.

For Differential thermostat for DIY solar systems

I needed a unit that could control a ventilator to cool down a room when it was colder outside than inside. This unit did the job.
I had god communication with the dealer. He made som modifications, so it fitet my needs.

Item arrived in good time and does exactly what it says.

For Differential thermostat for DIY solar systems

I am using thermostat to regulate transfer of hot air from top of sunny conservatory down a pipe via 2 in-line fans and through a wall into a living room.
Differential setting ensures efficient on/off periods to maximise heat transfer.
I am very happy with this neat and well made product.

Excellent product

For USB I2C module

It's an excellent product! I tested with several I2C products and it recognised them immediately.

As I have a Mac and the documentation only refers to Linux and Windows, here's a quick tutorial for the Mac:

You might have to install Python 3 and pyserial for Python 3, as macOSX defaults with Python 2.7.
Using macports:

# sudo ports install python36
# sudo ports install py36-serial

Check your dongle device name:

Manuels-iMac:usbi2c-python3-master mazevedo$ ls -l /dev/cu*
crw-rw-rw- 1 root wheel 21, 1 Jun 5 08:28 /dev/cu.Bluetooth-Incoming-Port
crw-rw-rw- 1 root wheel 21, 7 Jun 5 16:24 /dev/cu.usbmodem464B4301

Change the base scripts that contain the Linux code detection with macOSX (darwin) and the serial port address:

def serial_name():
if platform == "darwin":
return "/dev/cu.usbmodem464B4301"
else:
return "COM4"

Then just run:

Manuels-iMac:usbi2c-python3-master mazevedo$ python3.6 i2c_search.py
Connected to adapter with serial number: 464B430F
Searching I2C devices ...
0x40 (64)
0x70 (112)
Finished

It should work immediately.
