CR Series Lithium coin button batteries from Panasonic. These batteries are available in a variety of different sizes and capacity options to suit your application. These non-rechargeable batteries are ideal for smaller electronic devices and have a longer lasting life than alkaline equivalents. These batteries are small, round and slim and are normally used on their own but with their less self-discharge they are able to hold their charge for a longer period of time.

The 5A range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage.

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc.

This ACS721 current module is based on the ACS712 sensor, which can accurately detect AC or DC current.

The maximum AC or DC that can be detected can reach 5A, and the present current signal can be read via analog I / O port of Arduino.

With optocoupler isolation, the control signal and the power of the controlled device are isolated, which greatly increases the rigidity of the interference. PWM speed regulation widely used to control the start and stop of the motor. The signal input side can be welded to the terminal or pin itself, compatible breadboard output can be soldered to the terminal or direct wire.

MP3-TF-16P MP3 Disk TF Card Module Serial Port is a compact and inexpensive MP3 module that can be connected directly to the speaker. Module with battery power supply, speaker, the keypad can be used alone, or through the serial port control, as the Arduino UNO or any microcontroller with a serial port module. The module itself perfectly integrated hardware decode MP3, WAV, WMA.

While the software supports TF card driver to support FAT16, FAT32 file system. It can be done by simple serial command plays the specified music, as well as how to play music and other functions, without tedious low-level, easy to use, stable and reliable.

The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

If you are wandering to build a device that detects temperature and humidity from the atmosphere, then This sensor is needed for you.

The DHT22 Digital Temperature and Humidity Sensor Module AM2302 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

DS18B20 Temperature Sensor is suitable for the cold storage, granaries, storage tanks, telecommunications room, electric power room, cable trough, and other temperature measurement and control areas; bearing, cylinder, textile machinery, air conditioning, and other small space industrial equipment temperature and control; , Refrigerator, freezer, and low-temperature drying oven, etc. heating/cooling pipe calorie measurement, central air conditioning household thermal energy measurement and industrial temperature measurement and control and Many more..

This is DS18B20 Water Proof Temperature Probe – Black (1m) Original Chip which is based on the DS18B20 sensor.

It is very handy for when you need to measure something far away, or in wet conditions. Because they are digital, you don’t get any signal degradation even over a long distances.

These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter.

DS3231 RTC  is a Precise Real-Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C.
