This relay is based on ESP-01S WIFI module. It is designed for smart home, Internet of thing and other DIY project. With this smart relay, you will easy to DIY your smart switch to control any device by your phone anywhere. *Note: ESP8266 wifi module is not included
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
This is a small flat coin vibration motor with adhesive backing. Vibration motors are used today in an endless number of applications; these are quality motors used in medical, automotive, consumer, and industrial products.
A simple flex sensor, 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove.
This is a DC Mini Metal Gear Motor, ideal for making robots. Light weight, high torque and low RPM. Fine craftsmanship, durable, not easy to wear. With excellent stall characteristics, can climb hills easily. You can also easily mount a wheel on the motor’s output shaft.

This low cost yet powerful GPS receiver is based on the famous and high end u-Blox Neo-6M GPS module. It comes with small battery for hot-start, and there is built-in EEPROM too.
SIM900A Modem is built with Dual Band GSM/GPRS based SIM900A modem from SIMCOM. It works on frequencies 900/ 1800 MHz. SIM900A can search these two bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from 1200-115200 through AT command.
The TCS3200 color sensor can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.
GY-521 MPU6050 6DOF 3-Axis Gyroscope and Accelerometer Module is a carrier board based on MPU-6050 sensor which contains an accelerometer and a gyroscope. MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip.
ADXL335 triple axis accelerometer module provides easy access to the X, Y and Z axis analog outputs from the accelerometer. It is capable of sensing forces up to 3g in all axis. It can measure the tilt-sensing applications in the static acceleration of gravity, and movement, shock or vibration due to dynamic acceleration.
