1 x DHT-22 Digital temperature AND humidity sensor
Here we have a DHT-22 (also known as RHT03) Temperature and Humidity Sensor featuring a calibrated digital signal output with the temperature AND humidity sensor complex.
The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature.
A high-performance 8-bit microcontroller should be connected in order to get the most out of the sensor.
- 3.3-6V Input
- 1-1.5mA measuring current
- 40-50 uA standby current
- Humidity from 0-100% RH
- -40 - 80 degrees C temperature range
- +-2% RH accuracy
- +-0.5 degrees C
- long-term stability
- Reliability
- premium quality
- fast response times
- anti-interference
- high cost vs performance advantages.
- Relative humidity and temperature measurement
- The single-wire serial interface system
- signal transmission distance up to 20 meters
- extremely accurate humidity calibration chamber.
The DHT22's small size, low power, and array of features make it perfect for a variety of applications.
Typically you may want to wire your DHT22 as below.
We strive to post as fast as humanly possible, but sometimes we will only be able
to post your item the next working day after receiving payment.
In most cases we will post royal mail 1st class for orders within the U.K or Royal
mail airmail for orders outside of the U.K, unless otherwise stated. We strive to
make you as happy as we can, and therefore if you wish to make other postal arrangements
please contact us and we will see if we can oblige.
International customers please note: Airmail usually takes 3 to 5 working
days to arrive, but in extreme cases it can take up to 15 working days to arrive,
particularly if customs decides to inspect the package.
We try to be as green and non-evil as possible, and as such we tend to use as much
recycled materials in our packaging as possible. So you may receive your item in
a previously used envelope or bubble wrap.
By default we do not include a sales receipt in the packaging.
If you would like brand new packaging and bubble wrap and a receipt, then please
contact us upon ordering and I'm sure we could sort something out, and possibly
plant a tree to make up for it.
With the goal of making our customers as happy as can be, we work very hard to post
as fast as we can, communicate in the friendliest most helpful manner, and most
importantly, offer the best gear at the most competitive prices.
If however you are not happy in any way with our service or your item, then please
contact us before leaving average or even worse, negative feedback, and we will
do everything we can to resolve any issues.
In keeping with making you as happy as can be, we will in turn leave nothing but
the nicest, all-warm-n-fuzzy-inside feedback for you too.
If you are in any way unhappy with your purchase *gasp* then we will do all we can
to make you happy.
Just return your item in its original packaging, in the condition we sent it to
you in, and we will refund your money (less postage).
