DHT22/AM2302 Compatible Temperature and Humidity sensor module A DHT22/AM2302 or equivalent digital temperature and humidity sensor module, as described in the February 2017 "El Cheapo Electronic Modules" article. If you're using this to build the Altimeter/Weather Station from December 2017, you will need a 1k resistor wired between pins 1 and 2 and a 100nF capacitor wired in series with pin 4; see errata. Cat No SC4150. Price: AUD $9.00 1 In stock: yes (3 available).
