+150°C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits.

The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control

The UNO R3 is the most used and documented board of the whole Arduino family.\u003c\/span\u003e\u003c\/div\u003e\n\n\u003cp style=\"color: #333333;\"\u003eThe UNO R3 is a microcontroller board based on the ATmega328P. It has 14 digital input\/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eDifferences with other boards:\u003c\/strong\u003e\u003cbr\u003e\n\u003cbr\u003e\nThe UNO R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. \u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eRevisions:\u003c\/strong\u003e\u003cbr\u003e\nRevision 3 of the board (compared to Revision 2 ) has the following new features:\u003c\/p\u003e\n\n\u003cul style=\"color: #333333;\"\u003e\n\t\u003cli\u003e1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.

It is a low-voltage, low-cost, small-sized contactless card reader chip introduced by NXP for \"three-table\" applications. It is a good choice for the development of smart meters and portable handheld devices. The MF RC522 utilizes advanced modulation and demodulation concepts and fully integrates all types of passive contactless communication methods and protocols at 13.56 MHz. Supports 14443A compatible transponder signals. The digital part handles ISO14443A frame and error detection. In addition, it supports the fast CRYPTO1 encryption algorithm and verifies the MIFARE series of products. The MFRC522 supports the MIFARE series of higher speed contactless communication with bidirectional data rates up to 424 kbit\/s. As a new member of the 13.56MHz high-integration read-write card family, the MF RC522 has many similarities with the MF RC500 and MF RC530, as well as many features and differences.

Suitable for users of advanced applications such as device development and card reader development, and users who need to design\/produce RF card terminals. This module can be directly loaded into various reader molds. The module adopts a voltage of 3.3V, and can directly connect with any CPU board of the user through several simple lines of the SPI interface, which can ensure stable and reliable operation of the module and long reading distance; the module is easy to use, highly reliable and small in size.

measuring the speed of rotating assemblies where a magnet on the assembly alternately makes and breaks magnetic contact with the sensor as the assembly rotates.  They can also be used for applications such as determining when a door has been opened, position sensing and detecting the magnetic field created by current flow in a wire.\u003c\/span\u003e\u003cbr\u003e\n\u003cbr\u003e\nSenses relative

When no magnetic field is detected, the output will rest at approximately 1\/2 Vcc. If the south pole of the magnet is brought near, the output will linearly ramp towards Vcc and if the north pole of the magnet is brought near, the output will linearly ramp towards ground.\u003cbr\u003e\n\u003cbr\u003e\nIn the case of Vcc being 5V, with no magnetic field present the output will rest at about 2.5V. If the south pole of the magnet is brought near, the output will raise linearly up to a maximum of about 4.2V. If the north pole is brought near, the output will lower linearly to a minimum of about 1.0V.\u003cbr\u003e\n\u003cbr\u003e\nThe output is typically read by an ADC port on a uC if the strength or pole of the magnetic field is important. Optionally it can be run into a comparator like the LM393 if a digital output with an adjustable set-point is desired. If you are just counting the number of times a magnet goes by, this is easier than working with the analog output. Digital Hall-effect sensors are also available for this purpose.\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e \u003c\/div\u003e\n\n\u003cdiv\u003e\u003cspan face=\"Arial\"\u003eModel: 49E\u003cbr\u003e\nPackage: TO-92\u003cbr\u003e\nNumber of Pins: 3\u003cbr\u003e\nVoltage Supply: 3V~6.5V\u003cbr\u003e\nOperating temperature range: -40°C ~ +100°C \u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e \u003c\/div\u003e\n\n\u003cdiv\u003e\u003cspan face=\"Arial\"\u003e \u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e\u003cstrong\u003e\u003cspan face=\"Arial\"\u003ePackage included:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e10pcs 49E OH49E SS49E Linear Hall Effect Magnetic Sensor Switch Arduino\u003c\/div\u003e\n","brand":"Unbranded","offers":[{"title":"Default Title","offer_id":31011260432521,"sku":"q0M4v60dWaW09nk91","price":6.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0102\/3577\/2994\/files\/4126a670-629d-5df9-999a-82f51b1d7555.jpg?v=1738467992"}],"url":"https:\/\/www.eelectronicparts.com\/collections\/sensors.oembed?page=11","provider":"eElectronicParts","version":"1.0","type":"link"}
