+title: MaixCAM MaixPy Reading Thermography Sensor mlx90640
+---
+
+## Introduction
+
+MLX90640 is an industrial standard and fully calibrated 32*24 pixel thermal infrared array sensor.
+
+By attaching a thermography sensor mlx90640 to MaixCAM, you can obtain a 32x24 temperature data matrix (list[24][32]) by calling the `matrix()` method, which is suitable for applications requiring temperature data. The `image()` method can directly get the pseudo-color image that MaixCAM can display, equivalent to `obj.image_from(obj.matrix())`. The `xxx_temp_point()` method can get the values and corresponding coordinates of the minimum, maximum, and center temperatures in the most recent frame of data.

+title: MaixCAM MaixPy Using TOF Module OPNS303x for Ranging and Terrain Detection
+---
+
+## Introduction
+
+OPNS303x is a 100x100 TOF module, suitable for ranging or terrain detection.
+
+The current OPNS303x driver is compatible with OPNS3031 (the same model as MaixSense-A010).
+
+By connecting an OPNS3031 to MaixCAM, you can obtain a distance data matrix by calling the `matrix()` method, which is suitable for applications requiring distance data. The `image()` method can directly get the pseudo-color image that MaixCAM can display, equivalent to `obj.image_from(obj.matrix())`. The `xxx_dis_point()` method can get the values and corresponding coordinates of the minimum, maximum, and center point distances in the most recent frame of data.

+If you have a TOF requirement, please visit [Sipeed Store](https://wiki.sipeed.com/store.html) for inquiries and purchases.

+
+## 简介
+
+MLX90640 是工业标准并经过完全校准的 32*24 像素热红外阵列传感器.
+
+通过给 MaixCAM 外挂一个热成像传感器mlx90640, 调用 `matrix()` 方法可以获得 32x24 的温度数据矩阵(list[24][32]), 适用于需要温度数据的应用场景. 调用 `image()` 方法可以直接获取 MaixCAM 能显示的伪彩色图像, 相当于 `obj.image_from(obj.matrix())`. 调用 `xxx_temp_point()` 方法可以获得最近一帧数据中的最小最大以及中心温度的值和对应的坐标.
