W1209 Temperature Control Switch

Digital Temperature switch

DESCRIPTION The W1209 is a very low cost still highly practical a thermostat controller. With this module, one can control power to most types of electrical loads on the temperature sensor sensed by the supplied NTC temperature sensor. The best part is that for this no programming knowledge is required. 3 push button switches are used for configuring various parameters for on & off a relay triggered by changing temperatures. The relay switch contact handles a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3 digit seven…

Programless Robotics using stepper motor driver

Descriptions A very low-cost stepper motor driver that has 4 modes of operation. Can be used for excellent robotics application without using any program. 1.Working Mode: Normal Mode 1: S1 start stop button, S2 forward and reverse button, W2 potentiometer speed control. If limit reversal is required, two limit switches can be connected to the P3 pin, and the motor motion shaft is mounted with contacts, so that the motor will reciprocate within the stroke between the two limit switches. 2. Normal Mode 2: S1 forwards the start button, S2 reverses the start button, press any button to stop. W2…

Optical Liquid Level Sensor

One of the very low cost ($4) liquid level sensor with excellent performance. Unlike many liquid level sensors other than ultrasonic require probes to be inserted to the liquid. This causes electrolysis and after few days it stops working properly. Non touch-types Ultrasonic has the disadvantage of getting damaged if accidentally comes in touch with liquid or outdoor use. Presented below an optical sensor-based system that works on the principle of  IR light reflection and refraction through a prism.

Induction Cooking vs Gas cooking cost

Induction cooking is a method of heating an iron plate based utensil using magnetic induction. It heats the iron plate of the induction cooktop directly unlike a gas heating by flame for gas cooker. A lot of energy gets wasted in gas means of heating. Given a comparison between the Induction cooking vs Gas cooking of the two in terms of money spent it is seen that for the same item cooked by the induction way will cost 50% less money than non-subsidized gas means. Induction cooker price Buy here from Amazon best  ranging Rs1400 to 1700 https://amzn.to/2BZkHse     …
