Triple Axis Accelerometer Breakout
$8.72The Triple Axis Accelerometer Breakout is a small, low-power sensor that is used to measure acceleration in three dimensions. It consists of a micro-machined sensing element that is housed in a compact, leaded package, with leads that are used to connect it to a circuit. The Triple Axis Accelerometer Breakout measures acceleration along X, Y, and Z axes, and it outputs analog or digital signals that can be processed by a microcontroller or other control unit. The Triple Axis Accelerometer Breakout is commonly used in projects and applications that require the measurement of motion, such as wearable devices, gaming controllers, and other portable electronics.

TTP223B Capacitive Touch Sensor
$1.09This touch sensor is a capacitive touch sensor module and the sensor driver is based on the driver IC TTP223. This capacitive touch sensor is an ideal alternative for the old-fashioned keypads and buttons. The operating voltage of the TTP223 IC is from the 2V to 5.5V and the power consumption of the touch sensor is very low. Due to the inexpensive, low power consumption, and easy to integrate support, the touch sensor with TTP223 becomes popular in the capacitive touch sensor segment.

Ultrasonic Sensor Module HC-SR04
$6.54Ultrasonic Ranging Module HC-SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit
The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object – just like bats or dolphins do.
This module offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.
This sensor is perfect for collision avoidance on your next robotics or multirotor project!
