out-of-the-box sensor nodes ready for deployment

Question

I am on the lookout for sensor-nodes that do not require any DIY or sensor interfacing.

Purpose

This is because, at times one might just want to setup an IoT Network without having to program or interface certain sensors just to build a proof of concept

I wish to create a inventory summary for IoT Development (on the forum too via this thread) which have the following features:

1. Out-of-the-box or Off-the-shelf Products

2. Few Configuration Efforts for sensor nodes (via Apps or simple utilities)

3. deployment ready

4. No sensor shields or mounting sensor boards + programming

5. Avoid use of Gateways (WLAN Technology)

   a. If Gateway exist it should be out-of-the-box.

Are there some other nodes that are available with the following features?
