ASAIR Temperature and Humidity Sensor AM2302 (Original) The AM2302 is a wired version of the DTH22, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor . It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. Connect the red 3-5V power, the yellow wire to your data input pin, and the black wire to the ground. Although it uses a single wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin. Compared to DTH11, this sensor is more precise, more accurate, and works in a bigger range of temperature/humidity, but it's larger and more expensive. There is a 5.1K resistor inside the sensor connecting Vcc and DATA so you do not need additional pullup resistors. Also check the AM2302 Temperature & Humidity Sensor available on Iotcart. The sensor is suitable for 0-100 percent humidity readings with 2-5 percent accuracy and -40 to 80 degrees Celsius temperature readings with ± 0.5-degree Celsius accuracy. It has a sampling rate of no more than 0.5 Hz (once every 2 seconds) and comes in a 4-pin single-row pin package for easy connection.

ATmega162 The ATmega162 is a low-power CMOS 8-bit microcontroller based on the AVR-enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general-purpose working registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. In order to maximize performance and parallelism, the AVR uses a Harvard architecture – with separate memories and buses for program and data. While one instruction is being executed, the next instruction is pre-fetched from the program memory. Program flow is provided by conditional and unconditional jump and call instructions, able to directly address the whole address space. Most AVR instructions have a single 16-bit word format. Every program memory address contains a 16- or 32-bit instruction.
