BPW34 Silicon Photodiode Miniature Solar Cell
BPW34 is a PIN photodiode with high speed and high radiant sensitivity in miniature, flat, top view, clear plastic package. It is sensitive to visible and near infrared radiation with wavelength in the range of 430nm to 1100nm. Peak sensitivity is achieved at 900nm wavelength where it’s open circuit voltage is around 350mV for 1mW/cm2 light source. Several of these cells can be connected in series to provide enough voltage to power up an LED or so

DHT-11 Digital Temperature And Humidity Sensor
DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra 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). Its 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 in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity, but its smaller and less expensive

DS3231 Precise Real Time Clock Module I2C RTC AT24C32
DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line.Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensationDS3231 available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year.Clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output.
Address and data are transferred serially through an I2C bidirectional bus.A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failure, provide a reset output, and if necessary, automatically switch to the backup power supply.RST pin is monitored as generating μP reset manually.Save time and high precision addition, DS3231 also has some other features that extend the system host of additional features and a range of options.The device integrates a very precise digital temperature sensor, through the I2C * interface to access it (as the same time).Temperature sensor accuracy is ± 3 ° C. On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply.If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected.When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.
