This and several other segments have aired as part of WNYC’s Harlem Heat Project series. Tracking the heat in various locations in Harlem – indeed throughout the boroughs – is necessary to better understand the health and vitality of both the city and its inhabitants (many of these points are further elaborated in this post). Temperatures from a week in July for example ranged from around 80°F on the first floor to well over 90°F on some 7th floor locations!
And as it turns out the sensors they’re using are built in-part at least with Adafruit Feather boards – in conjunction with the DHT22 temperature-humidity sensor and a LiPo battery!

And hat-tip to John Keefe for blogging this and also linking to the code and BOM from his blog.
Featured Adafruit Products!
Adafruit Feather 32u4 Basic Proto: At the Feather 32u4’s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we’ve had tons of experience with as it’s the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. This chip is well supported in the Arduino IDE and can run just about every sensor/library out there.

Adalogger FeatherWing – RTC + SD Add-on For All Feather Boards: This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You get both an I2C real time clock (PCF8523) with 32KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS). Tested and works great with any of our Feathers, based on ATmega32u4, ATSAMD21, or ESP8266. Read more.
