PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

Detects sound that is greater than the ambient noise (adjustable sensitivity). Can operate from 3.3V to 5V.

Need something to sense distance, but you're expecting things to get a bit wet? Well look no further! This sensor can stretch all the way out to 4.5m in ideal conditions, with a resolution of 0.5cm...

Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This is an easy-to-use...

Vishay has a lot of light sensors out there, and this is a nice simple lux sensor that's easy to add to any microcontoller. Most light sensors just give you a number...

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor...

A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It’s so bad!

The Water Flow sensor measures the rate of a liquid flowing through it. The YF-S201 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler or anything else, and control the water flow rate to suit your needs!

BME688 sensor detects VOCs, temp, humidity, pressure. Supports Arduino/IoT via I2C/SPI. AI gas analysis for air quality & smart homes...

Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually...

Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This A01NYUB Waterproof...

The SHTC3 digital humidity sensor from Sensirion builds on the success of the proven SHTC1 sensor and offers consistent high accuracy within the measuring...

what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!
