+Linux Device Driver for AM2320 
+
+**Experimental**
+
+Tested on a Raspberry pi 3 with kernel version 4.4.14-v7+
+
+Usage
+------
+You need to have the proper kernel headers installed to build this driver. Use this tool to install kernel headers https://github.com/notro/rpi-source
+
+1. clone this repo 
+2. git clone linux-am2320-driver
+3. cd into directory
+4. type make
+5. sudo insmod am2320.ko
+6. type lsmod and see whether the driver is loaded properly
+7. sudo bash
+8. if you have a new Raspberry pi (B+, 2 or 3)
+
+  echo am2320 0x5c > /sys/class/i2c-adapter/i2c-1/new_device
+
+  else if this is a Rev. 1
+
+  echo am2320 0x5c > /sys/class/i2c-adapter/i2c-0/new_device
+
+Viewing measurements
+======================
+cat /sys/bus/i2c/devices/1-005c/temp1_input
+
+cat /sys/bus/i2c/devices/1-005c/humidity1_input
+
+OR

+
+To remove from kernel
+=====================
+sudo bash
+echo 0x5c > /sys/class/i2c-adapter/i2c-1/delete_device
+
+then do,
+
+rmmod am2320
+
+Cleaning the directory
