No pullup resistor needed. Just plug right in to Arduino or ESP8266. Description: Main Chip:AM2302 Temperature range: -40 to 80 degree celsius Temperature measurement accuracy: +/- 0.5℃ degree celsius Humidity measuring range: 0~100%RH Humidity measurement accuracy: ±2%RH Ultra-low power consumption No additional components Excellent long-term stability Single-bus digital signal output, bidirectional serial data Completely interchangeable Long distance signal transmission Size: 28 x 12 x 10 mm (L / W / H) Screw hole diameter: 2.6mm Weight: 4g Package included: 2* DHT22/AM2302 Digital Temperature Humidity Sensor Module 2* DuPont wire

Review: Convenient digital thermometer for Arduino like projects. - These work great. Only 3 wire saves a conductor. Easy to use, nice that they come with short cables to use during development. Arduino library makes interfacing easy.
Review: Accurate and easy with ESPHome and an Atom Lite - I'm a little new to the world of ESP and this was my first attempt to add something to my Atom Lites. But boy was it easy. I connected 3 Dupont wires from this to 5V, GND, and a GPIO pin on the Atom and was off to the races. Just added a handful of lines of YAML to ESPHome on Home Assistant and the sensors were created. Literally a 5 minute thing, plug and play - no resistor. In terms of accuracy, I have this and a Govee BLE an inch apart on my desk for a few hours and the Govee says 70.9 F and this is putting out 70.9 F. Govee humidity is 38% and this is 39%. If they aren't accurate, well they are identically inaccurate - and I think that is unlikely. Certainly you can find alternatives for a few dollars less, but I wanted no fussing and this delivered.

### ⭐⭐⭐⭐ proper supply voltage is crucial...
*by J***. on March 4, 2019*

I've bought two sets of these so far, they're reasonably consistent in regards to the reported values. And they're comparable to DHT22's sold by others. Which is good because I use a number of these throughout my home. And the readings are consistent between individual sensors and the reported values are also consistent within a reasonable range. The supply voltage is crucial to these sensors regardless of the vendor. The part (DHT22/AM2302 w/o a board) is spec'd 3.2 or 3.3 to 5 volts. If you are running one of these from a ESP-12E or other MCU with an integrated 3.3v regulator then chances are it will work without issue. And at 5v they'll work without any problems. However, I'm running them from an ESP-01 and external LM1117 regulator board where the regulator is an SMT part. There I've found that the regulators can be off and supply a voltage as low as 3.0 volts. NOTE: The ESP-01 supply voltage is spec'd at 2.7 to 3.6v or 3.7v, depending on the information source. When the supply voltage is at 3.2 or lower the device will not report correctly. Depending on the exact supply voltage the device may either not work at all or intermittently report "NaN" when using the Arduino library. The solution I found for my devices (ESP-01 + LM1117 SMT) was to supply the DHT22 with 5v and use a BSS138 circuit to handle the 3.3v VS 5v sides of the circuit. This has worked extremely well and a "test" device has been running 24/7 with the modified circuit for 3 months without any reading errors. Before that the error rate was about 20 to 50%. Bottom line, this is an excellent sensor for most hobbyist applications. It has the required resistor & capacitor already on-board and the connecting wires are a nice addition. However, for my application I would have preferred male/female wires instead of female/female. I will purchase these again the next time I need some.
