  • easy and fast to setup and use

    The biggest "pro" for this product that it has a onboard pul-up resistor. If you connect it to a Arduino or a Raspberry Pi there is no nead to use a seperate resistor between Vcc and signal. You can directly plug it to the board. There are alot of exampel codes writen on how to use this produkt and finnished programs you can call from your script/program.
    It would be even a better produkt if it hade some kinde of back cower for the circuiteboard. I will solder a cable direktly to the circuitboard and fasten it to a wall.
    Great product, a bit pricey. I needed a censor that could mesure bout negative and positive temperature. If you whant to log room temperature the DHT11 is cheaper.
  • Perfect sensor if you're building an Arduino based wether station

    The sensor if well supported by the Arduino platform. You can easily hook it up to an Arduino board. There are lots of tutorials for this on the internet. The sensor is also supported by a drop-in library by Adafruit. It took me just a few minutes to add this to my project.
    You can easily open the case with a sharp object and extract the circuit board and protect it with some epoxy lacquer. If you do this be sure to put some masking tape on the sensor before applying the lacquer or you will ruin it!
    Great buy for your DIY projects!
  • The most interesting sensor from the last time

    Very simple to use!Very cheap (although you can find cheaper).Well builted!Well documentated!Infinite and simple application!
    This is a very nice sensor. If you have a home garden or a especial flower (like an orchid) that needs full attention, you can automatize processes as irrigationor send signal saying that it needs water.It is made by: http://www.elecfreaks.com/store/octopus-soil-moisture-sensor-brick-p-422.htmland you can find all the documentation over therebasically it provides a analog output.when it's near to 0, means the soil is dry.when it's near to 900, means the soil is moist.I posted some photos for you to check the way i did itit's not necessary any arduino especial library,just basic analogic signal handling
    Buy this sensor if you want to have a home automation projector if you care with your garden/flowers but doesn't have time to keep checking on themtry the website i told you, you can buy it cheaper
  • Very useful sensor

    Temperature and humidity sensor very useful for measuring aaplicaciones in electronic equipment, ultra-low power which can be installed on portable equipment, good coverage that protects from bumps
    I would put a protection of cables and most suitable electric insulation on the data bus, and some form of external calibration
    The bottom line is excellent for measuring these parameters and make a datalogger equipment to sample and store temperature and humidity with a microcontroller.
  • Good sensor, very accurate

    More accurate than the little brother DHT11. If you are interested in 0.5 degrees, this is your sensor. Works well with the arduino's DHT library (there is a library for the DHT11, another for the DHT22 and a library for both --> saves bytes in your sketchs). Works with 3.3Volts and 5V. The sensor works well. Only 3 wires: GND, GCC and the signal.
    You can meter the temperature in 0.5 steps.
