Could someone suggest me some best magnetic sensors in terms of: 1. Good magnetic sensitivity ( should be able to detect vehicles) 2. Smaller in size.. and should be able to soldier on PCB 3. Consumes very less power / current typically in microA 4. Most importantly, temperature independent 5 works based on interrupt 6 x/y/z direction control

And also what are the best communication networks/ protocols for IoT in terms of :

1 reliability 2 medium range or long range 3 very smaller in size 4 consume very little power or current; in micro to 50 mA

Right now, we are using a NXPs FXOS8700CQ as a magnetic sensor but it badly depends on the temperature. Hence the results are very poor . To compensate it, sensor has to wake up every time per degree raise in temperature which consumes a lot of current. And Xbee is our current communication protocol. It consumes 40 mA current while transmission and less than 100 micro A in idle mode. But the realiability is the issue again. We are missing many packets and retransmission consumes a lot more current.

So please suggest or advice me if something works better than these and if there are any pulse based magnetic sensors available

 

lots of words
no numbers

For wireless protocols you have straight up Bluetooth LE + (Long Range with the newer silicon). If you want to do mesh then Bluetooth LE Mesh is doable. (though it's not as "smart" as other protocols) Another mesh protocol which routes your data more cleanly is Thread. You're not going to get as long rage with Thread though. What is "medium range to long distance?" There are other protocols not based on 2.5GHz like LoRA. It's good if you need long range but much more power hungry on transmission.

Like shteii01 said above, parameters rather than descriptions is helpful and necessary to find what you need.
