Cytotoxic spillmanagement ppt

power source and a 12v 2W LED as light source. To charge the battery i am using 12v 6W solar panels. to reduce the cost i am using a DC to DC buck converter as charge controller. it can boost 12v to 14v and prevent reveres flow of voltage with a high capacity diode

If everything is correct the circuit switch on the light at night and switch off and charge at the battery at day time. Just fix everything on a safe place and it work automatically

Today I am going to make life hack "instructable" can save both money and time. This is the tutorial of “how to make an automatic solar powered night light”. This device can charge at daytime and work automatically at night

This device has three circuits. a switching circuit. a solar charging circuit with battery and a LED night light circuit

After the one month test run i found out that these solar panels can’t fully charge the battery. Due to low current, battery needs 18 hours to fully charge the battery but sunlight is only available for 12 house max. in conclusion at the night time the switching circuit and LED light consume 10 to 12w of power from battery and at day time the solar panels refill the battery. Little bit tricky but its work!

I am using pre calibration just because of its simplicity in India cost of a variable resistor are 5 to 10 times higher than a single resistor

In pre calibration we use a single resistor with pre calculated resistance. in post calibration we use a variable resistor and calibrate circuit at final stage

LDR is the important component of this circuit. it will act as the dark sensor. There are two methods to calibrate the LDR one pre calibration and other one is post calibration

I am using a long two core coated wire to connect the LDR to main circuit. it will help to avoid the unwanted lights from other light sores

This Kit is designed for the clean-up of spills involving cytotoxic drugs. The Kit contains GREEN Z fluid control solidifier to contain hazardous chemical spills. For quick & easy clean-up and disposal with minimal exposure.

Connect your LDR to multicenter and find the maximum resistance(R max) at day time. Repeat the step at night time and find out the minimum resistance(R min)
