Experiments with ESP8266 ESP-01 variants

Understanding code :

Setting WiFi:

#define SSID "YOURSSID" /* replace YOURSSID with your WiFi access point name */
#define PASS "YOURPASSWORD" /* replace YOUR PASSWORD with your WiFi access point password */

PIR sensor calibration :

sensor_calibration (); 
/* It calibrates sensor for proper output. We need to power down PIRPIN before that */

WiFi Radio stat :

check_WiFi_radio (); /* Checks whether WiFi module is OK or not */
reset_wifi (); /* resets WiFi module to clear any problem */
set_wifi_mode (); /* Set WiFi module as client for connecting to Access Point */

check_wifi_stat (); /* Checks whether your WiFi module is connected to AP or not */
connect_ssid (); /* if not connected, then will connect with your connection parameter */

PIR data :

pirRead ();
/* reads PIR value, either 0 or 1. If 1, then Motion Sensed, if 0, then nothing is there */

Sending data to Pushbullet :

server_connect (); /* connecting to server */
post (); /* pushing notification to all devices */
server_disconnect (); /* close server connectioon */
