รายละเอียดสินค้า *****DS1302 Real Time Clock Module with Battery CR2032 โมดูล Real time clock ทำงานโดยใช้ DS1302 ซึ่งให้ค่าเวลาที่แม่นยำ และมีแบตเตอรี่สำรองที่ให้มาพร้อมกัน A Real Time Clock Module with battery backup using the easy to use DS1302 chip. The DS1302 chip uses a simple serial interface (see datasheet) and example code is available for Arduino, Raspberry Pi and many others. Features Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year with Leap-Year Compensation Valid Up to 2100 Serial I/O for Minimum Pin Count 2.0V to 5.5V Full Operation Uses Less than 300nA at 2.0V Single-Byte or Multiple-Byte (Burst Mode) Data Transfer for Read or Write of Clock or RAM Data Board Size: 44mm x 24mm Documents DS1302 Datasheet Arduino DS1302 Real Time Clock Using the Real Time Clock module on Raspberry Pi *****บทความสอนวิธีการใช้งาน RTC DS3231 กับ Arduino หรือ ESP8266 / ESP32 This is a module made using DS3231 RTC and AT24C32 EEPROM. DS3231 is an extremely accurate, low cost I2C RTC with integrated temperature compensated crystal oscillator. It also has a built in comparator which monitors the status of VCC to detect power failures and to automatically switch to backup power supply. AT24C32 provides 32,768 bits of serial EEPROM organized as 4096 words of 8 bits each. This gives you 32Kb of non-volatile memory for your projects. This module can be easily interfaced with Arduino Boards, Raspberry Pi and all Microcontrollers.

When buckle button batteries, even though the module is powered down, the clock will continue to chip timing. Module features are as follows: Can be timed to 2100 Control interface for the I2C interface 5VDC power supply recommendations DS1307 address of the module is 0x68 Level control interface for 5V or 3.3V 4 M2 screws positioning holes for easy installation Control Interface : A total of four pins (GND, VCC, SDA, SCL), GND to ground, VCC is the power supply, SDA I2C interface for the data lines, SCL of I2C interface clock line; Real-time clock IC : DS1307Z, independent timing, communication with the MCU via the I2C interface; Battery Holder : CR1220 battery holder, with the board presented the transposon inserted in the battery to allow continuous real-time clock chip timing. Positioning holes : 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination Experimental equipment : An Arduino-compatible motherboard Catduino (not familiar with open source hardware can be understood as Atmega328P microcontroller development board) and a mini USB cable; A real-time clock module; 4 Male to Female Dupont line for control interface and Catduino development board connected to the module; Experimental procedure : 1 with 4 Male to Female DuPont line real-time clock module and Catduino I2C interface to link up and make sure the battery has been installed on the module securely in the following table, shown in Figure ******HY-SRF05 โมดูลเซนเซอร์อัลตราโซนิก 5 pin hy - srf 05 sranging Description: This module performance is stable, precise measure distance.Can and foreign SRF05, SRF02 ultrasonic ranging module.Module with high precision, blind area (2 cm) very close, stable range is powerful according to the product to the market success! The main technical parameters: 1: using voltage: DC5V 2: the static current: less than 2 ma 3: high level output: 5 v 4: level output: 0 v 5: induction Angle: no greater than 15 degrees 6: detection range: 2 cm - 450 cm 7: high precision: up to 0.3 cm This product use: a mouth sends a high level of more than ten us, you can receive the mouth for high level output. To be able to open the timer timing, an output when the mouth into a low electricity at ordinary times you can read the value of the timer is here for the distance of time, can calculate the distance. So constantly cycle test, you can reach your mobile measuring the value of the ~ ~ Working principle of the module: (1) the IO trigger range, high level signal for at least 10 us; (2) module automatically sent eight 40 KHZ square wave, automatically detect whether there is signal to return; (3) have returne ******* Adapter บอร์ดอะแดปเตอร์ขยายขา ESP-32S , ESP-32
