  This module is based on a touch detection IC (TTP223B) of Capacitive type touch jog switch module . This module default output low, the low-power mode to mode; when a finger touching the corresponding position, the module will output high and returns low again touch. Mode is switched to fast mode; when for 12 seconds without touching, the mode and switch to low-power mode. The module can be installed such as plastic, glass surface non-metallic materials, in addition to the thin piece of paper (non-metallic) covering the surface of the module, as long as the touch of the correct position, you can make hidden in the wall, desk and other places button.     1.Size:15*11mm 2.Power:2.5-5.5V Trigger setting mode:(1->Short;0->No Short) AB=00:No-lock High TTL level ouput; AB=01:Self-lock High TTL level ouput; AB=10:No-lock Low TTL level ouput; AB=11:Self-lock Low TTL level ouput;

  A02YYUW Waterproof Ultrasonic Sensor is an easy-to-use commercial-grade sensor module. This module determines the distance to a target by measuring the time lapse between sending and receiving the ultrasonic pulse. The A02YYUW sensor features a waterproof and dustproof closed separated probe that is suitable for harsh and moist environments. All the signal processing units are integrated inside the module and the distance value is directly obtained through the Asynchronous Serial Interface. The A02YYUW communicates with the upper-host or other MCU with a 9600bit/s band rate that greatly shortens the developing cycles. Specifications 3.3V-5V operating voltage range <8mA average current 3cm blind zone distance 3cm-450cm detecting range (flat object) 100ms response time -15°C~60°C operating temperature rang...

  The HC-SR04 is an affordable and easy to use distance measuring sensor which has a range from 2cm to 400cm (about an inch to 13 feet). The sensor is composed of two ultrasonic transducers. One is transmitter which outputs ultrasonic sound pulses and the other is receiver which listens for reflected waves. It’s basically a SONAR which is used in submarines for detecting underwater objects. Here are its main specifications: Operating Voltage 5V DC Operating Current 15mA Operating Frequency 40KHz Min Range 2cm / 1 inch Max Range 400cm / 13 feet Accuracy 3mm Measuring Angle <15° Dimension 45 x 20 x 15mm The sensor has 4 pins. VCC and GND go to 5V and GND pins on the Arduino, and the Trig and Echo go to any digital Ard...

  This is jog type capacitive touch switch sensor module based on a touch detection IC TTP223B .  Normally, the output is low level(at mode of low power consumption). When the finger touch the corresponding location, output will be high(at quick speed mode). When the module do not be touched for 12 seconds, the mode would switch to low-power mode. It can be installed in the module, such as plastic, glass, non-metallic material surface. But not cover thin sheets(metal) on the surface of the module. Just touch the correct position, it can be hidden in walls, desktops and other parts to be buttons. Allows you to remove the troubles of conventional push-type buttons. Feature: Low power consumption Can replace the traditional key With four M2 screw holes, easy for operation Specification: Operating voltage: DC 2.0V ~ 5.5V VOH: VCC 0.8V VOL: VCC 0.3V Sink current: 8mA @ VCC = 3V, VOL = 0.6V Source current: -4mA @ VCC = 3V, VOH = 2.4V Response time: 220ms (at mode of low p...

 RTC module  is suitable for a wide range of projects, including clocks, timers, and alarms, as well as data logging and time stamping. This module is built around the highly capable DS1307 RTC chip and the AT24C32 EEPROM, At the heart of the module is a low-cost, extremely accurate RTC chip from Maxim — the DS1307. It handles all timekeeping functions and communicates with the microcontroller over I2C. The DS1307 can keep track of seconds, minutes, hours, days, dates, months, and years. It can work in either a 12-hour or 24-hour format and has an AM/PM indicator. For months with fewer than 31 days, it automatically adjusts the date at the end of the month, including leap year corrections (valid up to 2100). Another interesting feature of the DS1307 is the SQW pin, which can be programmed to output one of four square-wave frequencies: 1Hz, 4kHz, 8kHz, or 32kHz. The DS1307 IC incorporates a battery input for maintaining accurate timekeeping even when the device’...

  Today I made this Liquid Low level Alarm project. already I make one before to monitor a single Tank. But This will Monitor 4 liquid or water Tank. when any Tank reach Low liquid Level a sensor give signal to this device .so The warning Lamp related to that tank start blinking and an beeping Alarm sound also start. we can silence the beeper by pressing the push switch. and the indicator stay on until the liquid level normal.

 Many Industrial devices need li-ion battery packs for their backup power. after long use the battery pack may get old and should replaced with new battery pack. some times ready made battery pack not available in the market. so we can make one using proper li -ion batteries with BMS circuits.  These battery pack i made using spot welding machine in previous post
