This sealed Digital Temperature Sensor DS18B20 1 meter probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.
The MQ5 is used in gas leakage detecting equipment in consumer and industry applications,this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes and cigarette smoke. The sensitivity can be adjusted by the potentiometer.
Use this simple IR receiver for infrared remote control of your next project. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes.
Turn any USB port on a serial port to TTL level with this handy adapter. Ideal for communicating with interim or final circuits extremely easy via a USB port. The chip in charge of communications is PL2303HX Prolific. Comes with dupont type cables for easy connection, the user can provide their own cables to extend the connection distance.
Is there anything an Arduino can\'t do? Well, for one, most of them can\'t be powered directly from a 3.7V LiPo battery; much less charge and monitor that battery. The SparkFun LiPower Shield takes care of this by combining the functionality of two of our favorite battery power boards: the Power Cell and the Fuel Gauge.
This temperature amp; Humidity sensor is a wired version of the DHT21, in a large plastic body. It 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). Its fairly simple to use, but...
