RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects.
This is the ID-20LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing.
Power the module, hold up a 125kHz card, and get a serial string output containing the unique ID of the card.
Note: The new ID-20LA is essentially the same as the older ID-20, but has a lower input voltage.

The TMP102 is an easy-to-use digital temperature sensor from Texas Instruments. The TMP102 breakout allows you to easily incorporate the digital temperature sensor into your project.
While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I2C bus of the Arduino to communicate the temperature. Needless to say, this is a very handy sensor that doesn’t require much setup.

The HIH6130 is a digital output-type relative humidity (RH) and temperature sensor combined in the same package.
This allows the RH measurement to be temperature compensated and provides a second, standalone temperature sensor output.

The HMC6343 is a fully integrated high end electronic compass module that can compute and give you a heading direction that’s accurate within a couple degrees.
It is tilt compensated and is calibrated to handle magnetic distortions.
This breakout board allows for easy use of the HMC6343. All that is required is power and I2C connections to a microcontroller so that the module can receive commands and send data back to the user.
Product Code: SEN-12040Excl. VAT: £5.70 Incl. VAT: £6.84The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor.Add to Compare
