This is a low cost plastic gear RC servo with 1.80kg.cm holding torque (at 4.8V). It is a perfect solution for student robotic projects who build arms or linkages. The advantage of RC servo over the DC brush motor is the ability to control its rotation angle.
Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target.
The W1209 is an incredibly low cost yet highly functional thermostat controller. With this module (HCTHER0006) you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for...
Water sensor brick is designed for water detection, which can be widely used in sensing the rainfall, water level, even the liquate leakage. The brick is mainly comprised of three parts: An Electronic brick connector, a 1 MΩ resistor, and several lines of bare conducting wires.
This is a PP material float switch and contains no mercury. Light weight and simple working principle,high reliability. This float switch is a device used to sense the level of liquid within a tank,the switch may activate a pump,an indicator,an alarm,or other devices.
