3 axis accelerometer. +/-3g. Analog output.

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. 

A simple ambient light sensor.

A cadmium sulphide light dependent resistor (LDR) housed in a compact 5mm diameter package.

125 kHZ RFID Tag in the shape of a card.

This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

PIR Motion Sensor

The RHT03 (aka DHT22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature.

This is a force piezoresistive sensor. The harder you press, the lower the sensor's resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.

The HMC6343 is a solid-state compass module with tilt compensation from Honeywell. The HMC6343 has three axis of magneto, three axis of accelerometer, and a PIC core running all the calculations. What you get is a compass heading over I2C that stays the same even as you tilt the board.

The ADJD-S311-CR999 is a great little color light sensor. This evaluation board provides all the necessary support circuitry to discern the smallest differences between visible colors.

Honeywellin HMC5883L on 3-akselinen digitaalinen kompassi. Helppokäyttöinen kommunikaatio tapahtuu I2C-väylän avulla. Piirilevyllä ei ole jännitteenmuunninta, joten käyttöjännitteen tulee olla 2.16-3.6VDC.

This is a breakout board for Freescale's MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.

This breakout board makes it easy to use the tiny MMA8452Q accelerometer in your project. The MMA8452Q is a smart low-power, three-axis, capacitive micro-machined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data.

A simple flex sensor 5.6 cm (2.2") in length. As the sensor is flexed, the resistance across the sensor increases.

his is a simple breakout board for the ID-20 and ID-12 RFID readers. This board will bring the 2mm spaced pins out to two 0.1" spaced headers. You can solder the reader directly to the breakout board or use our 2mm sockets.

Breakout board fits within and under the ID-12. The board also works with the ID-20, but is smaller than the edges of the ID-20.

3 axis accelerometer. Two selectable measuring ranges (±1.5g, ±6g). Analog output.
