  • Perfect sensor if you're building an Arduino based wether station

    posted by anistor78 on 02:17:27 G5T 20/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 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.

    Cons: Since the sensor is supposed to sit in a potentially high humidity environment maybe it would be nice if the circuit board would be coated with some resin to protect it from oxidation.

    Other: Great buy for your DIY projects!

    posted by Briota on 14:26:52 G4T 16/04/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Good price - Easy to use - just conected the 3 wires, put a pull-up rezistor on between signal wire and +5V, uploaded example to arduino and everything worked.

    Cons: - found a better sensor for less price DS1820. These sensors can be connected all on a BUS (3 wires to all of them) - when connecting more than one sensor, each sensor needs its own digital pin

    Other: Just buy one to play with it.

  • Inexpensive drop-in replacement for DHT21

    posted by gigamegawatts on 17:28:39 G2T 18/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a drop-in replacement for the common DHT22 (aka RHT02) temperature/humidity sensor, but at half the price. I tried replacing a DHT21 in a sensor with this one, and the temperature and humidity readings are in-line with the DHT21. No downtime so far - quality seems to be good.

    Cons: None really. The DHT21 is a fussy sensor to program, requiring nano-second timing, so it's not the best choice for all platforms. But this product is 100% code compatible with a DHT21, and there is plenty of sample code to be found on the Internet.

    Other: This is the lowest price I've found for a DHT21 sensor, by far. You can find analog temperature sensors for less, but they are considerably less accurate. I doubt there is a cheaper humidity sensor out there.

    posted by kirovclass on 02:36:15 G12T 04/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Nice environmental sensor, it uses 1-wire protocol so simple to use, and also if powered at 5V the cable can be long up to 20m (according to datasheet). Good to have it also terminated with wires rather than headers/pins.

    Cons: For the price, nothing really.

    Other: Cheap sensor to use in any 'weather station' project. The possibility to have a long sensor wire is quite useful in order to keep only the sensor exposed (e.g. outdoor)
