The DHT sensor kit: three boards with large white sensor cages printed LONELY BINARY AM2302 DHT22, and three smaller boards with blue DHT11 cages, all on black PCBs with gold-plated borders, beside a teal box printed DHT SENSORS KIT.

You have this

DHT Sensor Kit: 3 × DHT22 and 3 × DHT11

Six single-wire temperature and humidity sensors on TinkerBlock boards: three DHT22s on the TK39, −40 to 80 °C to ±0.5 °C in tenths, and three DHT11s on the TK38, 0 to 50 °C to ±2 °C in whole degrees. The same four pins, the same fitted 10 kΩ pull-up and the same library; one word in the sketch says which one you wired.

Boards: 3 + 3DHT22 and DHT11
Wires: 3GND, VCC, DATA

The TK38 at an angle: a black board with a gold border and a blue DHT11 sensor cage with a grid of square vents lying flat across its top, two round mounting holes, DHT11 printed under the cage, GND, VCC, NC and DATA over four pads, a small resistor, lonely binary up the left edge, SINGLE WIRE up the right, and a right-angle four-pin header out of the front edge.

DHT11 Temperature and Humidity Sensor

Temperature: ±2°C, 0 to 50 °C
Humidity: ±5% RH, 20 to 80 %
Wires: 3GND, VCC, DATA
Supply: 3 to 5.5V; use your logic voltage
